Hey fellow developers! 👋 Just solved a classic frontend setup puzzle and thought I'd share in case anyone else is wrestling with the same issue. I was setting up Tailwind CSS in a React + Vite project and hit that frustrating wall where the styles just wouldn't apply. You know the feeling - you've followed the docs, everything looks right, but that beautiful blue bg-blue-500 just renders as plain white? Turns out I'd missed three crucial things: The content array in tailwind.config.js was empty (facepalm moment) - Tailwind needs to know which files to scan for class names! @tailwind directives need to be in your main CSS file (index.css, not App.css) Proper content paths: ["./index.html", "./src/*/.{js,ts,jsx,tsx}"] Complete PostCSS setup with tailwindcss and autoprefixer And of course, the classic "have you tried turning it off and on again?" (restarting the dev server) Sometimes it's the obvious things that trip us up! What's your most recent "aha!" moment with CSS tooling?  ( 6 min )

In this article you will get to know about the identity system and I will help you understand the basic fundamental concepts of the identity system. At the end of this article you will get the answers to the following questions: What is identity? What is authentication and authorization? What is access control? What are tokens? What is SSO? Now first let's start by understanding what identity is. Identity refers to the unique representation of a person or system within the digital ecosystem. For example: In real life your identity includes your name, fingerprint, photo ID, and in the digital world your identity includes your username, email, and user ID. Identity also includes some attributes which are known as identity attributes or claims. This is extra information about the user, for ex…  ( 8 min )

One of the most exciting parts of being a programmer is when you finally get to apply a concept you’ve learnt in a real-world scenario. In JavaScript, I learnt about higher order array methods like map() and filter(), but more importantly, how chaining them together might produce more sophisticated results, but it is one thing to know how these methods work, and another to solve an actual problem with them. That’s exactly what happened while I was building the multi-step form project from Frontend Mentor. I discovered a practical use case for chaining higher order array methods together, specifically map(). Here's a live demo of the project. Let's get into the nitty gritty In the 3rd step of the form, users are to select add-ons for their subscription plan. The application has two billing …  ( 8 min )

Understanding Raft: How Nodes Stay in Sync After Crashes In leader election systems, when one node goes down but the majority remain up, the leader can continue accepting and contributing new data. Example setup: node0 (leader) --- node1 (follower) --- node2 (follower) --- node3 (follower) Now imagine node3 crashes: node0 (leader) --- node1 (follower) --- node2 (follower) --- node3 (crashed) We see an error: err: node3 is down But that’s fine. As long as a majority of nodes (2 out of 3 followers) are still alive, the cluster continues contributing new data. Recovery scenario Let’s assume node3 comes back after five minutes. So what happens to node3 when it rejoins? Is it up to date? Obviously not, it’s missing those 3 contributions. The question is: how does node3 catch up with the rest of the cluster? The answer: Raft’s log replication Each contribution in Raft is stored in a log entry. i = log index t = term Before the crash After 3 new contributions Now the logs are inconsistent. That’s not what we want. How Raft fixes it When the leader sends the next log entry (say, i = 6), node3 pushes back: “Hey! My last index is 2, but you’re sending me index 6. Not acceptable!” The leader responds: “Ok, here’s the previous entry (i = 5).” But node3 complains again: “Wait… I only have index 2!” This back-and-forth continues until node3 receives a log entry with a matching previous index (i = 2). At that point, node3 accepts the next entries (i = 3, 4, 5, 6…) and catches up with the cluster. That’s Raft in action This process of syncing logs is how Raft ensures consistency across nodes, even when one crashes and comes back later. So in short: Raft uses logs to track contributions. When a node rejoins, the leader resends missing entries. The follower rejects mismatched logs until it finds the last known consistent entry. From there, it accepts new data and gets fully up to date. Hope you found this insightful! If so, leave a like and comment your thoughts below.  ( 7 min )

Everything you need to know about React Native and Android’s shift to 16KB memory pages — performance boosts, migration steps, and Play Store rules. If you ship React Native apps to Android, there’s a platform shift you can’t ignore: Android 15 introduces support for 16 KB memory page size. This brings measurable performance wins, but it also means some apps — especially those bundling native code (NDK/C/C++) — must be rebuilt or they won’t run on future 16 KB devices. The React Native team already added support in v0.77, so you’ve got a clear path. Let’s make sure you’re set up end-to-end. Google has also tied this to a Play publishing rule: starting November 1, 2025, any new app or update targeting Android 15+ must support 16 KB pages. Don’t wait for the deadline — do the checks now an…  ( 10 min )

Today's task is to create a hook to tell if it's the first render. The boilerplate code looks like this: export function useIsFirstRender(): boolean { // your code here } // if you want to try your code on the right panel // remember to export App() component like below // export function App() { // return your app { firstRender.current = false; }, []) return firstRender.current To know if we achieved our aim, we would display a message when the application renders. {firstRender: "First render" ? "Not first render"} We used a tenary operator which basically displays the first message if firstRender is true, or the second message if otherwise. The final code looks like this: import React, { useRef, useEffect} from "react"; export function useIsFirstRender(): boolean { // your code here const firstRender = useRef(true) useEffect(() => { firstRender.current = false; }, []) return firstRender.current } // if you want to try your code on the right panel // remember to export App() component like below export function App() { const isFirstRender = useIsFirstRender() return ( {isFirstRender ? "First render" : "Not first render"} ) } That's all folks!  ( 6 min )

I recently did a video tutorial on using jobs and queues in PayloadCMS and the solution I provide will not work in a Vercel deployment, runs locally and will probably also run on Railway because those are actual servers. This blog post explains why and walks you through how to update the project to run on Vercel. Get the source code here The "Why": Serverless vs. Long-Running Processes The code in the video uses Payload's built-in jobs queue, which relies on a long-running Node.js server process. The autoRun: true setting starts a persistent "clock" (setInterval) inside your server that checks every minute if a job needs to run. With Vercel, however, since it is a serverless platform, your code doesn't run on a server that is "always on." Instead, it's packaged into serverle…  ( 10 min )

Introduction At the turn of a new decade, prediction markets and forecasting platforms have emerged as one of the most innovative and intriguing applications of monetized information. By turning valuable information into tradable assets, these systems seek to crowdsource wisdom, aggregate probabilities, and - in some cases - challenge the accuracy and precision of even the most complex and sophisticated institutions. From drastic political changes to macro-economic indicators, weather events to corporate earnings, prediction and forecasting projects are steadily evolving into a new layer of financial and informational infrastructure by mastering the art of drawing parallel lines and connecting the dots between two or more seemingly unrelated events with uncanny precision and near-perfect…  ( 11 min )

This week's task turned out to be one of those that are easy to state and more challenging to do efficiently. Let's look at it. Task 1: Max Diff You are given an array of integers having four or more elements. Write a script to find two pairs of numbers from this list (four numbers total) so that the difference between their products is as large as possible. In the end, return the max difference. With Two pairs (a, b) and (c, d), the product difference is (a * b) - (c * d). Example 1: Input: @ints = (5, 9, 3, 4, 6) Output: 42 Pair 1: (9, 6) Pair 2: (3, 4) Product Diff: (9 * 6) - (3 * 4) => 54 - 12 => 42 Example 2: Input: @ints = (1, -2, 3, -4) Output: 10 Pair 1: (1, -2) Pair 2: (3, -4) Example 3: Input: @ints = (-3, -1, -2, -4) Output: 10 Pair 1: (-1, -2) Pair 2: (-3, -4…  ( 11 min )

While a privacy-first engineering architecture is the internal foundation of a trustworthy personal AI, it is insufficient on its own. To earn the confidence of users, enterprises, and regulators, this internal design must be validated by an external, verifiable governance framework.

Classification is the art of drawing boundaries. You take messy, high-dimensional data and force it into neat categories. In the wild, this could be spam vs. not-spam, cat vs. dog, tumor vs. healthy tissue. In textbooks, it’s often MNIST, the 70,000-image dataset of handwritten digits that’s become the “Hello World” of machine learning. MNIST looks simple, but it hides the essence of classification: Inputs: images, each a 28×28 grid of pixels → vectors in R784\mathbb{R}^{784}R784 . Outputs: 10 possible digits (0–9). Goal: learn a function f:R784→0,1,…,9f: \mathbb{R}^{784} \to {0,1,\dots,9}f:R784→0,1,…,9 . That’s it. Strip away the hype, and classification is about learning the function that maps features to labels. Think of classification as drawing walls in a hu…  ( 7 min )

At its core, workflow automation combines s…  ( 11 min )

Today I explored Rc, the Reference Counted Smart Pointer in Rust. This is where ownership gets interesting—sometimes a value might need multiple owners, and Rc provides exactly that functionality. Normally, ownership in Rust is strict: only one owner exists for any given value. But in real-world cases, multiple parts of a program may need to share access. For example, in graph structures, multiple edges may point to the same node. That node shouldn’t be deallocated until all edges stop pointing to it. Rc keeps track of the number of references to a value. Once all references are gone, the value is safely cleaned up. 👉 Think of Rc like a TV in a family room: everyone can watch while they’re in the room, and only when the last person leaves is the TV turned off. ⚠️ Rc works only in singl…  ( 7 min )

Quick Summary This article explores how to handle gaps in data and make sure your charts don’t quietly mislead. A must-read if you care about honest visual storytelling. Consider, the case of a line chart: where discrete data points are plotted along X and Y axes and connected to form a continuous line. Though the underlying grid may technically support an infinite number of coordinates, the chart typically displays only a finite set of values. The regularity of intervals between these points—along with axis labels and contextual annotations—enables the viewer to infer patterns and anticipate trends. On occasion, there exists an unexpected discontinuity—a gap in the data. When such an absence occurs without explanation, it can render the chart misleading, implying continuity where none …  ( 7 min )

Too often we see development teams struggle to finish a project. Here is a nice open-source framework I wrote to help with your upcoming microservices (or legacy!) project: the pipeline framework. https://github.com/mbarcia/CSV-Payments-PoC/tree/main/pipeline-framework Welcome to the Pipeline Framework - a robust, scalable, and maintainable solution for processing data through a series of steps with built-in benefits for high-throughput, distributed systems. Step-based Processing: Each business logic operation is encapsulated in a step that implements a specific interface. Reactive Programming: Steps use Mutiny reactive streams for non-blocking I/O operations. Type Safety: Steps are strongly typed with clear input and output types that chain together. Configuration Management: Steps can be configured globally or individually for retry logic, concurrency, and more. Observability: Built-in metrics, tracing, and logging for monitoring and debugging. It doesn't ask for much, only that you translate the business case into a "pipeline" model with each step having a defined input/output. You only write the business logic for each step and the framework will do all the Kubernetes heavy lifting for you (messaging, auto-persist, error handling, etc.) I'm in the process of making it an independent set of JARs on Maven central. At the moment it is included in the "CSV Payments Processing" system which is its "reference implementation". Reach out to me in the comments if you would like to know more. Cheers.  ( 6 min )

Networking forms the backbone of our digital world. Ever wondered how your messages, photos, or games travel across devices? Behind the scenes, two frameworks make it possible: the OSI Model and the TCP/IP Model. This guide breaks them down with easy analogies, and comparisons. 🧩 What is the OSI Model? A theoretical, 7-layer model designed by ISO to standardize communication. Each layer has a unique role, from presenting the message to physically sending it. Layers (Top → Bottom): Application Presentation Session Transport Network Data Link Physical 👉 Analogy: Sending a letter Write the letter (Application) Package it neatly (Presentation/Session) Route it through the postal system (Network) Deliver it to the house (Physical) 🚚 What is the TCP/IP Model?

The next evolution of LLM-generated code or code modification isn’t another fine-tuned model, nor is it a singular new tool or a tool chain. The next evolution of LLM code generation is going to be much deeper than you expect. To solve this, we need to understand that this is a multidimensional problem that LLMs cannot solve because they lack the ability to think, rationalize, and infer meaning. Cursor, Windsurf, Codex, and cli tools like Gemini/Claude/Warp all do the same thing with a different coat of paint. They all optimize context stuffing, and not in a cost-effective manner. Here is the hard truth: context stuffing is meaningless without understanding the application as a whole, and we will continue to see inferior outputs from LLMs. I am sure that many of you who Vibe Code (myself…  ( 9 min )

If you’re running a startup and handling customer data—especially the sensitive stuff like personal or financial info—you really should start thinking about SOC 2 compliance sooner rather than later. It’s not just another boring checkbox. SOC 2 is actually a big deal for building trust with customers and standing out from the crowd. Even if you’re hustling to grow fast, skipping compliance now can come back to bite you when you start chasing those bigger deals. When you get SOC 2 compliant, you’re showing clients and investors you actually care about security. That can help you close deals faster and just feel a bit more confident as you grow. Honestly, it might sound like a hassle at first, but if you tackle it the right way, it doesn’t have to be overwhelming. Getting a head start means …  ( 8 min )

On Day 4 of my Python challenge,I learned about type casting. Type casting means converting one data type into another for example, changing a number into text, or text into a number (if possible).This is super useful when working with user input or combining different kinds of values. Here’s the code I wrote today: # Integer to float num_int = 10 num_float = float(num_int) # Float to integer decimal_num = 5.9 whole_num = int(decimal_num) # Number to string age = 22 age_str = str(age) # String to integer num_str = "100" num_from_str = int(num_str) print("Integer to float:", num_float) print("Float to integer:", whole_num) print("Number to string:", age_str) print("String to integer:", num_from_str) What happened when I ran it? Notice how the data type changes when we cast it: int → float adds a decimal (10 → 10.0) float → int drops the decimal part (5.9 → 5) int → str turns numbers into text (22 → "22") str → int only works if the string is a number ("100" → 100) GitHub update: git add 'day4(type_casting).py' git commit -m "type casting..." git push Challenge for you: Try converting "3.14" into a float. Then convert it into an integer.What result do you get? Your turn: Have you ever had a situation where you needed to convert data types (maybe while coding, or even thinking about real life like changing “22” to 22 😉)?Share your examples in the comments!  ( 6 min )

The Silent Data Loss Problem Every Multi-User App Faces Multi-user applications have a dangerous default behavior that many developers don't realize until it's too late. When multiple users modify the same data simultaneously, the last person to save wins, and everyone else's changes disappear without a trace. Silent data loss. No exceptions thrown, no error messages, no warnings - just data quietly vanishing. The good news? EF Core has a built-in solution that requires just one attribute. In multi-user applications, the default behavior is deceptively dangerous.

In the ever-evolving landscape of software development, quality assurance is the foundation of reliable products. Among the many testing approaches available, white box testing stands out as one of the most thorough and transparent methods. Unlike black box testing, which focuses only on external behaviors and outcomes, white box testing opens up the software like a glass container—allowing testers and developers to peer into its inner logic, execution paths, and architecture. Why is this important? Because modern applications are no longer simple. They’re complex systems running on microservices, integrating with external APIs, handling sensitive user data, and needing to meet both performance and security demands. Testing only at the surface level isn’t enough. To truly ensure trust, per…  ( 10 min )

TLDR Treat prompts like code. Version them, test every change, ship through environments, and trace what’s happening in prod. Use a Git-style workflow for prompts, semantic diffs, templates, environment-aware rollouts, and CI/CD with automated and human evals. Layer in observability and a gateway for rollback, routing, and cost control. If you’re building with LLMs, you already know: prompts are code, but they drift like data. One “tiny” change to a prompt or variable can tank accuracy, spike latency, or blow up costs. If you don’t have version control for prompt management, you’ll get regressions, brittle prompts, and bugs you can’t reproduce. Here’s the playbook: Version prompts with structure.

TL;DR Modern browsers are unreliable for large file downloads from dynamic or expiring links because they can't properly resume failures. This note provides two Windows batch scripts (for wget and aria2) that solve this problem. Using session information (HTTP headers and cookies) extracted from your browser's dev tools, these scripts can robustly resume downloads, even if the link needs to be refreshed. Modern web browsers often fail to robustly download large files (e.g., OS images) over unreliable or slow connections. There are two primary reasons for this: Limited Resume Capabilities: Standard browser downloaders often cannot properly resume a failed download, deleting the partial file and forcing a restart. Dynamic & Expiring Links: Many services no longer provide direct download …  ( 9 min )

Picture this: you're doom-scrolling through Instagram at 2 AM—that special hour when algorithm logic meets sleep-deprived vulnerability—when you encounter an environmental activist whose passion for ocean cleanup seems absolutely bulletproof. Her posts garner thousands of heartfelt comments, her zero-waste lifestyle transformation narrative hits every emotional beat perfectly, and her advocacy feels refreshingly free from the performative inconsistencies that plague so many human influencers. There's just one rather profound detail that would make your philosophy professor weep: she's never drawn breath, felt plastic between her fingers, or experienced the existential dread of watching Planet Earth documentaries.

Web components are dead, hail to web components! I think that you should follow me in their recovery. I’m talking about “vanilla” JavaScript here (or, at least, TypeScript) and not about frameworks such as Angular, React, or Vue.js. You can easily integrate them, if you need to, later on. You can find lots of articles on web components here on the DEV Community, but to be honest I see that they’re not so popular anymore among developers. I don’t even remember the first time I heard about them, but I think they still matters: I do believe in a web where they can be exchanged between different projects. This is something that belongs to the open source contibution. A new Hacktoberfest will begin soon, and I will talk about it, so it’s time to consider the topic. Let’s say I’m working on a co…  ( 7 min )

Introduction Coffee shops are booming in my area. Every month, I hear about a new one opening, which makes me wonder: Will these business last long? Or are they just part of a seasonal hype? This curiosity inspired me to create an AI agent that can explore the coffee shop market and predict its potential success. While I'm focusing on coffee shops in this project, the same framework can be applied to other businesses, such as restaurants, salons, gyms, and retail stores. However, because LLMs are limited by their knowledge cutoff dates, having access to real-time data is crucial for obtaining the most up-to-date insights. Traditionally, entrepreneurs relied on guesswork, small surveys, or costly market research. Now, thanks to tools like Google Maps and Google Reviews, we can access real…  ( 12 min )

For clean installs of macOS or installs on multiple computers with only one download, creating a bootable macOS installer on a USB drive is the way to go. Up to Sequoia, Apple released standalone installers for the major releases of macOS on the App Store. For Tahoe, however, there's no such thing and probably never will. The installer is available on third-party download sites, but it is an incredibly bad idea to use any of them, no matter how trustworthy it may look. Just don't do it! Also, there's no reason to take such unnecessary risks – with a little help of the Terminal. You'll need a big enough USB drive. Use the Disk Utility to erase it to HFS+ format and the default name /Volumes/Untitled. Then launch the Terminal and: # Find the installer for the version of macOS you wish to install softwareupdate --list-full-installers # Download the installer app softwareupdate --fetch-full-installer --full-installer-version {VERSION} # Create a bootable installer on the USB drive: sudo "/Applications/Install macOS {MACOS_NAME}.app/Contents/Resources/createinstallmedia" --volume /Volumes/Untitled That's it, easy as 123 and free as in free beer! I won't go into much detail here, but the basic steps are as follows: Create a Time Machine backup. Create a second, full backup using SuperDuper, Carbon Copy Cloner or a similar tool. Make sure you have successfully completed the steps 1 and 2. Attach the USB drive containing the installer. Shut down your Mac, then restart it into boot options: On an Apple Silicon Mac, push and hold the power button. On an Intel Mac, push the power button, then hold the option key (⌥). Use the Disk Utility to erase the startup disk to APFS. Use the macOS installer on the USB drive to clean install macOS. Migrate your data from one of the backups onto the fresh macOS.

In open source projects, time is precious. Maintainers juggle bug fixes, feature requests, community support, and documentation, all while trying to keep code secure and releases organized. One repetitive but crucial task is reviewing pull requests and preparing release updates. It's necessary, but it eats up hours that could be spent innovating. In our work at CAMEL-AI, open-source contributions move fast. Every week, our team spends time reviewing pull requests, highlighting key changes, and preparing release notes. It’s important work, but also repetitive — hours get lost in scanning PRs, checking impact, and formatting updates. This time, instead of doing it manually, we asked ourselves: what if a multi-agent system could take over this process? That’s when we decided to try it with Ei…  ( 13 min )

The Basics of File Handling in Python Python provides powerful tools for working with files, allowing you to read and write data effortlessly. Let's dive into the fundamentals of file handling in Python. Opening and Closing Files Before you can read or write to a file, you need to open it using the open() function. Remember to close the file using close() once you're done to free up system resources. file = open('example.txt', 'r') Reading from Files You can read the contents of a file using methods like read(), readline(), or readlines(). Experiment with these methods to extract data efficiently. with open('data.txt', 'r') as file: Writing to Files To write to a file, open it in write or append mode and use methods like write() or writelines() to add content. Don't forget to handle exceptions using try-except blocks. try: Manipulating File Pointers You can move the file pointer using methods like seek() to navigate within a file. This allows you to read or write at specific positions. with open('data.txt', 'r') as file: Advanced File Handling Techniques Working with Binary Files Python supports reading and writing binary files using modes like 'rb' and 'wb'. This is useful for handling non-textual data like images or executables. Handling Exceptions When working with files, it's essential to anticipate and handle exceptions like FileNotFoundError or PermissionError. Use try-except blocks to gracefully manage errors. Using Context Managers Context managers, implemented with the with statement, ensure that files are properly closed after use, even if an exception occurs. This simplifies file handling and improves code readability. Conclusion Python's file handling capabilities empower developers to work with external data seamlessly. By mastering file operations, you can efficiently manage file I/O tasks and build robust applications. Experiment with different file handling techniques to unleash the full potential of Python!  ( 7 min )

The video game industry has always been driven by innovation. From the pixelated worlds of the 80s to today’s hyper-realistic virtual environments, developers continually push the boundaries of what’s possible. One of the most important aspects of creating an immersive experience is realistic game physics—how objects move, collide, and interact in a digital world. Traditionally, game physics relied on pre-defined rules, mathematical models, and rigid simulation engines. While these approaches provided consistency, they often lacked the flexibility to replicate the chaotic, unpredictable nature of the real world. This is where Machine Learning (ML) is reshaping the industry. By training algorithms on real-world data and using adaptive models, machine learning can create physics that feels n…  ( 9 min )

This is a story of rewriting an application for DI containers, parsing dependencies, drawing schemas to avoid getting lost, and quietly praying to every possible deity that nothing suddenly crashes.

I recently worked on a project that let me explore some exciting areas like: Building Telegram bots Using WhatsApp APIs Playing with asynchronous programming Developing and consuming APIs The result? 👉 WATele-Bridge – a simple, self-hosted bridge between Telegram and WhatsApp. The project has two main parts: Telegram Bot (Python, Telethon) Listens for new messages from a user-specified chat, group, or channel. Whenever a new message arrives, it triggers an event handler. That event makes an HTTP request to an API endpoint. WhatsApp API (Node.js, '@whiskeysockets/Baileys') Exposes a send-message endpoint. Receives the incoming request from the Telegram bot. Forwards the message directly to WhatsApp. This essentially creates a Telegram → WhatsApp relay. I wanted to: Learn Telethon for Telegram bot development. Explore Baileys (a popular WhatsApp Web API library). Understand how to design async message handling. Practice building and integrating a small microservice API. It’s a great project if you’re curious about combining different chat platforms or experimenting with real-time communication apps. You can self-host the project with the instructions in the repo: This is still a work in progress, and contributions are very welcome. Some possible improvements: Adding support for two-way sync (WhatsApp → Telegram) Deployment scripts (Docker, PM2) Better logging and error handling Adding the ability to listen from multiple Telegram chats This was a fun experiment that combined multiple APIs and asynchronous programming. If you’ve ever wanted to link two messaging platforms, this project might give you a head start.  ( 6 min )

When your system grows to millions of users, even the simplest operations—like checking if a phone number or email already exists—can become costly. Yes, you can add database indexes, but every lookup still eats up I/O and CPU cycles. Under heavy signup traffic, this can quickly overwhelm your database. This is where Bloom Filters come to the rescue. 🌸 A Bloom Filter is a probabilistic data structure used for set membership checks. It allows us to ask: 👉 “Does this value possibly exist?” It can say: ❌ Definitely Not → Safe to skip DB. ✅ Might Exist → Confirm with DB. This tiny compromise (allowing false positives, but never false negatives) gives us O(1) lookups with very little memory usage. At its core, a Bloom filter is just: A Bit Array (size m) → starts with all 0’s. k Hash Function…  ( 9 min )

Connecting an ultrasonic sensor like the common HC-SR04 to an Arduino Uno (or any similar board) is a fundamental project. The process for an "Arduino Uno32" is identical to a standard Arduino Uno, as the pin functionality and voltage levels are the same. Here is a clear, step-by-step guide. 1. How an Ultrasonic Sensor (HC-SR04) Works VCC: Power (5V) Trig: Trigger Input Pin Echo: Echo Output Pin GND: Ground It operates by: You send a short 10µs HIGH pulse to the Trig pin. The sensor sends out an ultrasonic burst (8 pulses of 40kHz). The sensor then sets the Echo pin HIGH. It keeps the Echo pin HIGH until the burst reflects back and is detected. You measure the duration the Echo pin was HIGH. The longer the duration, the farther the object. You then calculate distance using the speed of so…  ( 8 min )

Had a background job in Kubernetes. Super simple - check for pending work every 5 minutes: setInterval(() => { checkPendingJobs(); // Send emails, process data, cleanup tasks }, 5 * 60 * 1000); Deployed to 3 pods for "high availability." Big mistake. Monday morning: Users getting duplicate emails, database CPU spiking. Checking logs: Pod-A: Processing job #123 - sending welcome email Pod-B: Processing job #123 - sending welcome email Pod-C: Processing job #123 - sending welcome email All 3 pods wake up at the exact same time, query the database, find the same pending jobs, and process them in parallel. Classic race condition. Tried database locks. Tried Redis locks. Tried leader election. All complex, all brittle. Then realized something obvious: Why am I trying to coordinate 3 workers when I only need 1 job to run? Deleted the setInterval. Made it an HTTP endpoint: app.post('/jobs/process', async (req, res) => { await checkPendingJobs(); res.json({status: 'done'}); }); Added external scheduler (GCP Cloud Scheduler): gcloud scheduler jobs create http my-job \ --schedule="*/5 * * * *" \ --uri="https://myapp.com/jobs/process" That's it. Scheduler hits the endpoint, load balancer picks one pod, job runs once. No race conditions possible - only one request Way less code - no coordination logic Better reliability - managed scheduler vs app timers Easier debugging - clear request logs Works everywhere - AWS EventBridge, cron, whatever Stop asking "How do I coordinate multiple instances?" Start asking "Do I need multiple instances doing this?" Most background jobs are perfect for external triggers: File processing → storage events Cache warming → deployment hooks Cleanup tasks → schedulers Health checks → external monitoring Been running this for months.

Introduction A database schema defines how data is organized within a relational database; this is inclusive of logical constraints such as, table names, fields, data types. A star schema is a data modeling technique for data warehouses that features a central fact table surrounded by several denormalized dimension tables , resembling a star. It is a multi-dimensional data model that is an extension of a star schema, where dimension tables are broken down into subdimensions. In summary, star schemas offer simplicity and fast query performance, while snowflake schemas provide a normalized structure that saves space but adds complexity. The choice depends on your specific data needs.  ( 6 min )

I’ve just completed the coding and initial training of a Convolutional Neural Network (CNN) on my dataset. The model is designed for image classification and follows a standard architecture: several convolutional layers extract features from the images, followed by pooling layers to reduce dimensionality. The extracted features are then flattened and passed through fully connected layers, ending with a softmax output for classification. The code handles data loading, preprocessing, model definition, training, and evaluation, and I’m now able to make predictions on new images with the trained model. The CNN gives a solid baseline, but for more complex datasets or higher accuracy, more advanced architectures can be beneficial. My next step will be working with EfficientNet-B2, a state-of-the-art CNN model pre-trained on ImageNet. EfficientNet often outperforms standard CNNs because it scales depth, width, and resolution more efficiently, which usually results in better accuracy with fewer parameters. I’m excited to see how it improves the model’s performance on my dataset. Stay tuned for updates on the EfficientNet training and results!  ( 6 min )

Exception handling is essential for building robust, user-friendly APIs.

ResourceNotFoundException A custom exception helps you signal specific error cases (like a missing resource) in your business logic. // filepath: src/main/java/com/example/exception/ResourceNotFoundException.java package com.example.exception; /** * Thrown when a requested resource is not found. */ public class ResourceNotFoundException extends RuntimeException { public ResourceNotFoundExc…  ( 7 min )

Another week, another update! I could kind of improvise on how to position a big object in the middle of the screen. For example if the window width is 1280 and the board width is 150 I'd take half of 1280 which is 640 and subtract 150 from it and set it as the X coordinates of the board because the top left side of the object is the starting point I also learned how to handle bounces in a somewhat easy way which I'll talk about in a later section And I faced quite difficult ones! Firstly it's not really a problem but I would always forget to call the functions after making them. Then when I'd run the code I'd be surprised that why something isn't working Another one, which I mentioned earlier was the collision of the ball with the player board and the window. This one took the most brain work out of me and took a while for me to come up with a solution that would meet my standards. Good question, friend. Now I wanna implement more things to it that I have in mind such as: PLAYER 2 and it's controls, probably a net and a "field" between the 2 players, and in general a touch up to the whole game to make it look more like a 2 player tennis game. Until next week, stay safe, and take care of yourselves!  ( 6 min )

After months of grinding, I thought I was ready. For a final check, I set up a mock interview with a friend who had just joined Microsoft. It went well enough. I solved the algorithm, explained my approach, and wrapped up on time. But then I asked them a simple question: “Did I justify my decisions well enough?” They gave me a generic answer and moved on.

We’ve all grown accustomed to operating as guests in digital spaces owned and controlled by others, where terms of service can shift, content can be moderated, and data can be harvested at will. The tragic assassination of conservative activist Charlie Kirk has not only reignited urgent debates about political violence and online rhetoric but also underscored the critical necessity for individuals to carve out their own independent digital domains. Charlie Kirk, the co-founder of Turning Point USA (TPUSA), was a prominent and often polarizing figure known for his outspoken conservative views. He built a signi…  ( 9 min )

If statements are one of the most common constructs in programming — but they can get messy fast. Nested ifs, long logical chains, and hard-to-read conditions make code brittle and harder to maintain. Luckily, binary algebra (Boolean algebra) provides a powerful set of tools to simplify these conditions. Let’s break this down in a beginner-friendly way. Binary (or Boolean) algebra deals with values that can be either true or false. The three basic operations are: AND ( ∧ ) – true only if both sides are true. OR ( ∨ ) – true if at least one side is true. NOT ( ¬ ) – inverts the value (true becomes false, false becomes true). In most programming languages, these are written as: && for AND || for OR ! for NOT Binary/Boolean Algebra have set of rules to implement : Consider this code: if ((is…  ( 7 min )

If you’re new to Kafka, you’ve probably asked yourself: “When a producer sends a record, what does Kafka actually store on disk? Is it JSON? Avro? Hex? Bytes??” I recently went down this rabbit hole myself — so here’s a breakdown of what really happens behind the scenes. Bytes Let’s clear the air first: Kafka doesn’t know or care about JSON, Avro, Protobuf, POJOs, or unicorns 🦄. It only deals in byte arrays (byte[]). Producer sends: byte[] key, byte[] value Broker writes to log: byte[] Consumer reads: byte[] Everything else (JSON, Avro, Protobuf, String) is just a serialization format layered on top. Two words that get thrown around a lot: Serialization = turning an in-memory object (like a Java POJO) into a storable/transmittable format. Encoding = mapping characters into bytes…  ( 7 min )

Hallo world! Pada postingan ini kita akan membahas gimana cara membedakan partisi LVM atau bukan. Pertama kita bisa menggunakan lsblk tools. Jalankan perintah berikut lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT Jika outputnya ada LVM2_member, berarti partisi itu dipakai LVM. tapi kalau langsung ext4, xfs, btrfs, berarti bukan LVM. Atau berikutnya bisa menggunakan pvdisplay, jalankan perintah berikut pvdisplay Jika ada output (nama PV, VG, LV), berarti ada LVM, tapi jika kosong maka sistem tidak pakai LVM. Oke selanjutnya kita akan bahas gimana cara resizenya. Kita samakan asumsi, disini saya ingin memperbesar partisi root dari 300GB ke 600GB. Sebelumnya saya sudah memperbesar size disknya via proxmox management web ui. Jadi seharusnya jika di cek dengan fdisk akan ada perubahan size. Meskipun sizenya telah berubah tapi ini belum bisa di pakai. Karena jika di cek dengan df -h size / masih sama belum ada penambahan kapasitas. Ok, dari studi kasus di atas kita akan coba memperbesar kapasitasnya dan meminimalisir downtime. langsung saja ke caranya Pastikan partisi root, cek dengan: lsblk Lihat mana yang dipakai untuk / (root), pada kasus ini root berada di /dev/sda1. Lanjut resize partisi /dev/sda1, gunakan tool growpart, jika belum ada toolsnya install dulu: apt install cloud-guest-utils -y lalu jalankan growpart /dev/sda 1 Itu akan memperbesar partisi /dev/sda1 supaya sesuai dengan ukuran disk baru (600GB) Setelah resize partisi baru kita resize filesystem, jika filesystem kita ext4, maka jalankan resize2fs /dev/sda1 Tapi jika filesystem kita xfs, maka jalankan: xfs_growfs / Setelah sudah, selanjutnya cek hasil df -h Sekarang harusnya kapasitas root berubah jadi 600GB. Ringkasnya: Proxmox GUI berhasil resize disk (600GB sudah terbaca). Ubuntu VM partisi root masih 300GB, harus di-extend manual dengan growpart + resize2fs. Semoga bermanfaat dan selamat mencoba.  ( 7 min )

A browser builds a webpage step by step: Reads the HTML file top to bottom. It converts the text into tokens, then into the DOM tree. If the browser encounters a tag without async or defer: It pauses HTML parsing immediately. Downloads the JavaScript file (if external). Executes that JavaScript. Only after execution finishes does it resume building the DOM. Because JavaScript can modify the DOM or CSSOM while the page is loading. For example: Hello Hello . Hits → stops everything. Downloads + runs big-script.js. 4 After execution → continues parsing . appears later, delaying rendering. Case 2: Script with defer Hello tag until that script is fully executed.  ( 6 min )

Imagine you're sending an important letter to a friend through the mail. Before sealing the envelope, you take a photo of the letter. When your friend receives it, they take another photo and send it back to you. If the two photos match, you know the letter arrived untampered and intact. If they don't, something went wrong during transit—perhaps the letter was altered or damaged. In the digital world, checksums serve a similar purpose. Just as photos verify the integrity of a physical letter, checksums answer the question: Has this data been altered unintentionally or maliciously since it was created, stored, or transmitted?

Debugging GPU code can be more complex than debugging CPU code due to several factors inherent to the massively parallel nature of GPU computations and the distinct architecture of GPUs. Here are some of the biggest challenges and strategies to overcome them: Massive Parallelism: GPUs execute thousands to tens of thousands of threads concurrently, making it harder to understand the state of the program at any given time. Traditional debugging techniques like stepping through code or examining variable values become impractical due to the sheer number of threads.

1️⃣ What is SSA? SSA is a way of representing code where: Each variable is assigned exactly once. If a variable is reassigned → the compiler creates a new “version” of that variable (x1, x2, x3 …). When there are multiple control-flow branches (if/else), the compiler uses a φ-function to “merge” values back together. 🔎 Note: SSA is not a new kind of IR on its own, but rather a specialized form of IR. Compilers convert their Intermediate Representation (IR) into SSA form to make analysis and optimization easier. Original code: x = 1; x = x + 2; y = x * 3; After converting to SSA: x1 = 1; x2 = x1 + 2; y1 = x2 * 3; Original code: if (cond) { x = 1; } else { x = 2; } y = x + 3; After converting to SSA: if (cond) { x1 = 1; } else { x2 = 2; } x3 = φ(x1, x2); y1 = …  ( 7 min )

In the fast-paced world of web and mobile application development, delivering a seamless user experience is just as important as ensuring functional correctness. While traditional functional testing focuses on verifying if buttons work, forms submit correctly, and pages load as expected, it often overlooks a crucial aspect — how things look on the screen. This is where visual testing steps in. Visual testing goes beyond checking functionality; it ensures that the application’s user interface (UI) appears as intended. It helps detect visual bugs like misaligned elements, overlapping text, incorrect fonts, broken layouts, or color inconsistencies — issues that functional tests usually miss.

As blockchain moved from curiosity to mainstream, its environmental footprint sparked crucial conversations. This piece distills what “green blockchain” means, why it matters, and how the industry is steering toward energy efficiency without sacrificing security or decentralization. Many blockchain networks rely on a mechanism called Proof of Work (PoW). In PoW systems, independent participants (miners) compete to solve math puzzles, and the winner gets to add the next block of transactions to the chain.

How to Search Electronic Components and Where to Find Them 1. Start with the Part Number The fastest way to search for an electronic component is by using its Manufacturer Part Number (MPN). For example, instead of searching for “ARM processor,” type “RK3588” or “STM32F103C8T6.” This eliminates ambiguity and helps you locate the exact product. If you don’t have the exact part number, try searching by: Manufacturer name + product family (e.g., "Texas Instruments LM317") Functional description (e.g., "3.3V voltage regulator, 1A") Several online platforms aggregate information from global distributors, making it easy to compare availability, pricing, and datasheets: Findchips – Searches multiple distributors, shows pricing, inventory, and alternatives.

Modern websites often rely on heavy visuals to engage users. On platforms like puzzlefree.game, high-quality puzzle images are essential to the experience—but too many large images can slow down performance. That’s where lazy loading comes in. It’s a technique that delays the loading of images until they are actually needed on the screen. While it improves speed, developers sometimes worry: does lazy loading hurt SEO? Let’s find out. Lazy loading is a web performance optimization technique that prevents images (or other resources) from being loaded until the user scrolls near them. Example with the modern HTML attribute: Faster initial load: The browser loads only what’s visible, reducing time to interactive. Better Core Web Vita…  ( 7 min )

The idea was to help developers share their code with AI assistants like ChatGPT. As someone who often struggles to explain my code structure to AI, I needed to build a tool that could take an entire project and package it into a single, readable text file. I chose Node because I'm comfortable with JavaScript, and Node has great built-in modules for file system operations. Setting up the GitHub repo was straightforward - picked the MIT license, wrote a basic README, and I was ready to code. The required features came together piece by piece: CLI Arguments: I discovered Commander.js, which made parsing command-line arguments trivial. Git Integration: This was trickier. I used Node's child_process to run git commands and parse the output. The challenge was handling non-git directories grace…  ( 6 min )

Managing multiple apps and libraries can be frustrating. Luckily, Lerna makes monorepos not just possible, but actually enjoyable. 🔹 Why Use Lerna? Let’s say you have this structure: /root Your package.json might look like this: "workspaces": { Now, add Lerna scripts: "scripts": { Run npm run start → both app1 and app2 start together. 🎉 🔹 Monorepo vs Polyrepo Monorepo: All apps + libs under one root Polyrepo: Each app/lib in its own repo With Lerna, the monorepo approach gets easier — single place to manage dependencies, build, and publish. 🔹 Bonus: Module Federation Even though everything lives in one repo, with Webpack Module Federation, you can still load code at runtime across apps. Think: shared components between app1 and app2 without re-building everything. 🎯 Wrap-up Lerna simplifies building, testing, and publishing packages in a monorepo.

Hello dev.to community! 👋 Yesterday, I explored Terraform, a powerful Infrastructure as Code (IaC) tool for provisioning cloud resources. Today, I’m diving into Ansible, a widely used tool for automating server configuration, application deployment, and orchestration. 🔹 Why Ansible Matters While Terraform creates infrastructure, you still need to configure servers and applications running on them. That’s where Ansible shines: ✅ Agentless → Works over SSH (no agents to install) 🧠 Core Ansible Concepts Inventory → Defines your servers (hosts file with IPs/domains) Modules → Reusable units to perform tasks (install package, copy file, etc.) Playbook → YAML file describing tasks to apply to hosts Roles → Structured way to organize playbooks for reusability Ad-hoc Commands → Quick one-liners for immediate actions 🔧 Example: Simple Playbook name: Install Nginx on Ubuntu hosts: webservers become: yes tasks: name: Install Nginx package apt: name: nginx state: present 👉 Run with: ansible-playbook -i hosts install_nginx.yml This will automatically install and configure Nginx on your defined servers. 🛠️ DevOps Use Cases Automated server provisioning (installing software, setting users, configuring firewalls) Application deployment (Java, Node.js, Python apps) Managing secrets and configs Works great with Terraform → Terraform provisions infra, Ansible configures it ⚡ Pro Tips Use Ansible Galaxy for community roles (huge time-saver 🚀) Store playbooks in Git for collaboration and version control Integrate with Jenkins / GitHub Actions for automated deployments Secure credentials using Ansible Vault 🧪 Hands-on Mini-Lab (Try this!) 1️⃣ Install Ansible on your machine 🎯 Key Takeaway: 🔜 Tomorrow (Day 18): 🔖 #Ansible #DevOps #Automation #IaC #ConfigurationManagement #SRE  ( 7 min )

The Problem with the Classic Game Loop 🎮 Almost every interactive application, from video games to user interfaces, relies on a continuous execution loop. This loop is the heart of the application, responsible for everything from updating the game state to rendering graphics. While it's a fundamental concept, the traditional approach can often feel like a point of contention among developers. Why? Because the classic game loop, often a simple while(true) or while(IsRunning) block, can quickly become an unmanageable monolith. Consider a typical game loop: void MainGameLoop() {     Initialize();          while (IsRunning)     {         ProcessInput();         UpdateGameState();         RenderGraphics();         PlayAudio();         // ...and a dozen other things     }          Shutdown();…  ( 10 min )

When I first containerized my Node.js app, I felt pretty good about myself. I had a Dockerfile, I built it, and it worked. Then I checked the size. 1.2GB. For a single Node.js service. That’s when reality hit me. My image wasn’t lean—it was obese. It slowed down builds, bloated my CI/CD pipeline, took forever to push to the registry, and ate storage like there was no tomorrow. So, I put my Docker image on a strict diet. After a few rounds of optimizations, it went from 1.2GB → 250MB → 54MB. Here’s the story of how I cut the fat—and how you can too. Here’s what my original Dockerfile looked like: FROM node:16 WORKDIR /app COPY package*.json ./ RUN npm install COPY . . CMD ["node", "server.js"] Looks innocent, right?

Why Would We Want to Create a MCP Server? Creating a MCP server allows us to connect an LLM or AI to real-time data, personal data, or other data sources. I previously wrote a post where I explain how the Model Context Protocol (MCP) works internally; you can check it out if you’re not satisfied with just a recipe and want to learn more. In this post, I’ll detail how to create a MCP server. We’re going to make one that solves one of the most embarrassing LLM errors: not being able to count the number of r’s in variations of the word strawberry. For example: strawberrrry or strawberrrrrrry. If you’re not a bot, you already know that counting letters is a pretty trivial task for a human. On the other hand, for an LLM it’s almost impossible due to how it works—based on tokens. AI can create…  ( 9 min )

If you've just... Completed a bootcamp (like me!) Graduated with a CS degree Studied coding independently You probably have mostly been either pushing to your main or creating a development branch that you merge into main. Once you start working in groups, things get a little more complicated. Whenever you get on a new team, don't forget to ask and observe what their best practices are for git hygiene, branch naming, and merge requests! This video is a great overview. Essentially - rebase allows you replay your commits on top of the latest main - rewriting history to be clean and linear. Merges would create a merge commit and preserve commit history. Most teams might choose to rebase, unless you're working on open source. 1: Sync your local main with the current remote main git pull origin…  ( 8 min )

A friend recently came to me with a problem. The first design looked simple: store a row in MySQL for every (user_id, category_id) pair and update it whenever something changed. But in production, things broke badly. Their schema looked like this: category_user_read ( user_id BIGINT, category_id BIGINT, read BOOLEAN, PRIMARY KEY (user_id, category_id), FOREIGN KEY (user_id) REFERENCES users(id) ); The logic was: When a user opened a category, update their row with read = true. When a new post was added, update all rows in that category with read = false. Simple enough, right? In practice, this design was a database bottleneck: Every page view triggered an update. Every new post triggered a mass update across potentially millions of rows. InnoDB placed exclusive row locks fo…  ( 7 min )

You’ve been here before. It’s 2:17 AM. Your phone screams into the silence of the night. The dashboard isn't just red; it's a crimson waterfall of failed jobs. A dead queue. A poisoned message. A downstream API that decided to take a permanent vacation. You sigh, not just at the broken system, but at the tedious, manual recovery you're about to perform. Again. We treat these systems as necessary plumbing—unglamorous, hidden, and only noticed when they leak. But what if we reframed it? What if building a fault-tolerant, self-healing job processing system wasn't a chore, but our masterpiece? Not as engineers, but as artisans of resilience. This is the story of that journey. From a fragile, static sculpture to a living, breathing ecosystem. Every great artwork begins with an intention. Our co…  ( 9 min )

You don't just build an API. You begin a relationship. It starts with a handshake—a contract. A promise of functionality, of data, of a service rendered. You extend this promise to your consumers: other teams, third-party developers, even your future self. For a while, it’s perfect. The code is clean, the responses are elegant, and the world makes sense. Then, inevitably, the world changes. A new feature demands a new field. A performance overhaul requires a structural change. A legacy parameter name, chosen in haste years ago, now feels embarrassingly naive. You must evolve. But how do you move forward without breaking the handshake? How do you innovate without betraying trust? This, fellow engineers, is where we transition from mere coding to artistry. Implementing API versioning isn't a…  ( 9 min )

This isn’t just another “we taught AI to answer reviews and now everything is magic ✨” story. Nope. This is about building a custom ticketing system for a support team—complete with business rules, multiple LLMs (ChatGPT and Gemini), and real humans doing quality control (because let’s be honest, AI still occasionally hallucinates ). User feedback is basically free consulting. Entire industries (gaming, foodtech, SaaS, e-com, delivery—you name it) thrive or crash based on what customers type into a review box: ratings, rants, bug reports, thank-you notes, and sometimes, full-blown essays. Each one is a signal telling you whether your product is a rocket ship 🚀 or a sinking boat 🛶. And those signals? Yeah, they’re multiplying faster than npm packages.

O que é um ledger? Considere um Ledger como um "livro da verdade", por exemplo, uma planilha contábil de uma empresa, onde são registradas todas as transações que aconteceram. Assim como em uma planilha contábil, não editamos ou removemos registros, apenas adicionamos novas entradas. Isso nos garante a imutabilidade, que é um ótimo princípio em sistemas financeiros. A forma mais comum de tratar isso é por meio de eventos de entrada e saída, junto ao montante de valor correspondente para cada transação. Como fazer? Minha recomendação é a abordagem de Event Sourcing com snapshots. A ideia é ter uma entidade responsável por armazenar as entradas, que deve ser "append-only". Muitos bancos de dados SQL e NoSQL fornecem mecanismos para permitir apenas escritas incrementais e leituras. Atravé…  ( 7 min )

A brutally honest story of building a full-stack app in the AI age - where every "firts commit" typo and late-night debugging session reveals what we're really signing up for It was August 20th, 2025, 11:47 PM. I typed git commit -m "firts commit" and hit enter. Yes, "firts." With a typo. Because apparently, even in the age of AI coding assistants that can write entire applications, I still can't spell "first" correctly when I'm excited about a new project. That typo-laden commit would become the first of 94 commits across 27 days - a journey that perfectly captures the paradox every developer faces in 2025: AI tools promise to make us faster and smarter, but somehow we're still debugging our own mistakes at 2 AM, wondering if we're more productive or just more confused.

I’ve been getting more and more requests lately to build custom booking systems with admin panels that manage records and directories. This comes up a lot in B2C services — think beauty studios or clinics — where the admin panel has to be quick to build, affordable, and seamlessly integrated into existing workflows. Nobody wants to spend weeks training staff or risk disrupting daily operations. Most aggregator platforms stick to a linear model: one specialist, one service, one time slot. Sounds simple — until you need to handle group bookings or overlapping workflows where one staff member is involved in multiple stages of a procedure. Throw in the constant stream of changes — cancellations, reschedules, service swaps — and you quickly realize: the system has to react instantly and update …  ( 9 min )

The Unified Auditing feature in Oracle Database is a powerful mechanism for capturing database activity in a centralized and consistent way.

When I first saw the problem statement on EWskills “extract a nibble from an 8-bit register”, I thought this would be easy. After all, a nibble is just 4 bits, right? But along the way, I discovered I had several gaps in my understanding — not just about bit manipulation, but also about how hexadecimal numbers, masks, and C syntax really work. In this post, I’ll walk you through my confusion, how I corrected my thinking, and what I learned about firmware development in C. We are given: An 8-bit register value (0–255). A position: 0 means extract the lower nibble (bits 0–3). 1 means extract the upper nibble (bits 4–7). We need to return the nibble value as a decimal number (0–15). Input: reg = 0xAB, pos = 0 Output: 11 Input: reg = 0xAB, pos = 1 Output: 10 At first, this confused me. Let…  ( 8 min )

I made a benchmark for "discernment" several months ago — how well can a model judge. It has been the most accurate predictor of the utility of a model in agents and coding that I have seen to date. It turns out that discernment is incredibly important when writing software, and models with poor discernment may be good at the syntax but they are terrible at the broader task of engineering. See, the role of software engineer, when done properly, is not primarily about pounding out syntax. Being good at typing and syntax is just a prerequisite to do the real job: pathfinding in an infinite problem space. The primary skill that all good senior engineers have is an above average ability to make subjective judgment calls at each step of the problem solving process. Given two or three iterations, a good senior engineer's solution approaches the optimal path. Not that dissimilar from a great race car driver finding the optimal racing lines on a given track. To make coding models faster, more token efficient, and cheaper to operate — they often are trained, and reinforced, with code, code and more code — and if we were training a race car driver, this would work great. However, unlike the racetrack, the solution space of coding is infinitely vast — discerning a path through it efficiently leverages everything we know, everything we are. In other words: I can't explain why organized sports, reciting Shakespeare, memorizing scripture, or playing the piano makes you a better engineer, but it does. Along with brute experience, it is those seemingly unrelated disciplines that shape and craft your ability to make judgment calls. To discern. The same is true for models. Stripped down and efficient models can be excellent at various discrete tasks, but finding an elegant solution to a hard problem? Nah, turns out you need to know how to change a diaper at 3am to do that well.  ( 6 min )

When we talk about habit trackers, most people imagine a simple checklist. Over the next 20 days, I'm sharing every step of building a Habit Tracker with: Next.js for the frontend (fast, SEO-friendly React framework) Fastify for a high-performance Node.js API MongoDB + Mongoose for flexible, schema-driven storage This post documents Stage 1 - Planning & Data Design, the foundation that sets the tone for the whole project. My goal is a lean first release that's still valuable: Create & edit habits - simple CRUD with validation Daily logging - mark each habit as done/not-done per day Weekly & monthly summaries - quick analytics for motivation Staying focused here keeps scope tight and shipping fast. Next.js: server-side rendering and API routes for snappy UX Fastify: modern, lightweight, and faster than Express MongoDB/Mongoose: flexible schema with room for growth I debated Express vs. Fastify for a while; Fastify's plugin ecosystem and performance won. Three main collections emerged: User: auth info and settings Habit: name, description, schedule DailyLog: user-habit-date relationship + status Indexes were planned early for quick weekly/monthly queries. Plan indexes first: analytics speed depends on it. Keep MVP honest: say "no" to nice-to-have features until the core is proven. The entire codebase and documentation are public: GitHub Repo I'll push updates daily as I tackle UI, API endpoints, testing, and deployment.

Internet of Things (IoT) The Internet of Things (IoT) refers to a network of physical devices—such as home appliances, vehicles, and mobile phones—that are embedded with software, sensors, and connectivity features. These capabilities enable the devices to collect and share data across networks [1]. IoT devices are the physical objects that make up this network. For example: A smartphone can be used to record tutorial videos (data collection). These videos can be transferred to a computer (data sharing). Finally, the content can be uploaded to YouTube or other platforms (further data collection and distribution). Big Data refers to datasets that are too large, too fast, or too diverse to be handled effectively by traditional methods [2]. It is not only about size, but also about how we…  ( 7 min )

The Evolving Landscape of Code Software development is in a constant state of flux. The practices that defined excellence a decade ago are now foundational, and the tools we once considered revolutionary are today's standard issue. We've moved far beyond simply writing code that works. Modern software development is an intricate dance of speed, security, user experience, and scalability. To understand where we are heading, we must first appreciate the pillars supporting today's most successful software projects. These are not just buzzwords; they are fundamental principles that drive quality and efficiency. The days of monolithic, multi-year projects with a single "go-live" date are largely over. Agility is the reigning philosophy. Methodologies like Scrum and Kanban have broken down ma…  ( 10 min )

If you’ve ever been happily styling your Django project and then suddenly lost all your CSS and JavaScript after setting DEBUG = False, you’re not alone. This “disappearing static files” issue is one of the first surprises many Django developers run into when moving from development to production. Let’s unpack why this happens, and how to fix it. DEBUG = True When you’re building locally with DEBUG = True, Django’s runserver is designed to make your life easier. It automatically serves your static files using the django.contrib.staticfiles app. You don’t need to configure anything special — your CSS, JavaScript, and images just show up. This is fine for development. But Django’s philosophy is that in production you should use a dedicated web server or middleware for serving static files.…  ( 7 min )

Jenkins has long been a go-to tool for Continuous Integration and Continuous Delivery (CI/CD). But as projects and teams grow, the way we manage jobs in Jenkins has changed drastically. Let’s explore the shift from Freestyle Jobs to Pipeline as Code (Jenkinsfile), why it matters, and how it fits into modern DevOps practices. Freestyle jobs are often the first step when learning Jenkins. They allow engineers to quickly configure tasks such as compiling code, running tests, or deploying applications. Everything is set up through Jenkins’ graphical interface. For small projects or experiments, this approach feels straightforward and effective. However, the simplicity of Freestyle jobs comes with limitations. Since the job configuration lives only inside Jenkins, it cannot be version-controll…  ( 8 min )

Quando falamos de um loop for, podemos inicializar diversas variáveis, definir condições de continuidade para todas elas e atualizá-las a cada iteração do loop. Isso é útil para problemas que envolvem iterações dependentes de múltiplas variáveis ou para manipulações complexas de dados. #include int main() { for (int i = 0, j = 10; i < j; i++, j--) { printf("i = %d, j = %d\\n", i, j); } return 0; } Nesse exemplo, i é inc…  ( 9 min )

You’ve learned how to store data in lists, transform them with comprehensions, and sort them with built-in functions. But what if you only need a specific part of your data? How do you extract the first three items, the last two, or even reverse a list without a loop? This is where slicing and indexing come in—a concise and powerful syntax for accessing sequences with surgical precision. 1. Indexing: The Foundation Indexing is how you access a single element in an ordered sequence (like a list, tuple, or string). Python uses zero-based indexing, meaning the first element is at position 0. message = "Hello" my_list = ['a', 'b', 'c', 'd', 'e'] print(message[0]) # Output: 'H' print(my_list[1]) # Output: 'b' You can also use negative indexing to count from the end of the sequence. -1…  ( 8 min )

Consolidating Knowledge and Engineering for the Future Introduction Day 10 of the DFIR Lab Challenge concluded with an emphasis on introspection and progress. On that day, I put all of the knowledge and abilities I had acquired during the challenge into one cohesive package, went over the engineering choices made in various builds, and pinpointed areas that needed improvement. The main objectives of the session were to optimize data pipelines, fine-tune detection criteria, and ensure that the lab setup was scalable and robust. By taking a step back, assessing the progress, and planning for the future, the lab was transformed from a simple practice setting into a strong basis for continuing education in digital forensics and incident response.

The Illusion of Storage What if I told you that your most important passwords don't exist anywhere? Not in your password manager, not in encrypted databases, not even in your own memory. They were always there, waiting to be discovered. This isn't magic—it's cryptography. And it's based on the same radical principle as my Chrono-Library Messenger: the information already exists; we're just learning how to access it. Think about how password management works today: You memorize → Human memory is fallible You store → Databases get breached You encrypt → Encryption can be broken You transmit → Interception risks exist Even the most secure password managers ultimately rely on storing something somewhere. But what if we could remove storage entirely? Just as with Chrono-Library Messenger, whe…  ( 9 min )

Agriculture is one of India’s oldest industries, but today it’s also one of the fastest-evolving. From AI-powered soil testing to IoT irrigation systems, agritech startups are driving efficiency and sustainability. Yet, when it comes to financing, many founders hit the same challenge: lack of collateral. That’s where credit guarantee schemes come in. These programs reduce the risk for lenders, making loans more accessible for early-stage entrepreneurs. The Problem: High-Risk Perception in AgriTech Most banks hesitate to lend to agri-focused startups because: Cash flows depend on unpredictable harvest cycles. Collateral (land, machinery, assets) is often missing. Technology adoption in agriculture is still considered risky. Result? Many founders bootstrap or rely on small grants, limitin…  ( 7 min )

Introduction AI has gone way beyond autocomplete. With agentic AI models now capable of writing code, testing it, and even deploying applications, developers everywhere are asking: Do we still need to write code ourselves? Some predict the death of coding as a profession, while others believe AI will make developers 10x more productive. Let’s explore both sides. The Case for "AI Will Replace Coders" 1. Agents can already complete tasks 2. No-code + AI convergence 3. Economics favor automation The Case for "AI Will Empower Coders" 1. Oversight remains essential 2. Complexity needs human reasoning 3. History repeats itself What Developers Are Experiencing Pro-AI: Some teams report cutting sprint timelines in half using Copilot Agents or GPT-powered assistants. Skeptical: Others find AI-generated code harder to maintain, leading to more bugs later. Reality: It depends on whether AI is treated as a junior dev or as the entire dev team. How to Future-Proof Yourself Instead of worrying, focus on skills AI can’t easily replace: AI Collaboration Skills → Learn how to prompt, guide, and review AI effectively. System Design & Architecture → Think beyond code; design scalable systems. Agentic Workflows → Experiment with AI as “your dev team,” not just a tool. Conclusion: The 10x Future AI won’t kill coding. It will kill the way we code today. The best developers won’t be the ones who write the most lines of code. They’ll be the ones who can leverage AI to deliver value faster, cleaner, and smarter. So the question isn’t: Will AI replace developers? Will you adapt and become a 10x AI-powered developer?

I have this thought in my mind for a while. I don’t want to sound pretentious or anything. I just feel that the svelte development experience was ruined for my when runes start. I know that stores are still a thing, and I can use it without issue. However more and more we are moving out of that. We have great articles talking about observables, and stores in svelte. Here some of that: Stores are great to architecture a site and make sure that it works. I work for more than a year in a Gigantic svelte project. The main problem I look was bad use of stores, why? Mentally shift was not happening. Everyone still thinking on values not observables. We are building the UI, so when we are working of stores we need to think in everything as a observable.

I worked as an engineeer manager in a large e-commerce company in Saudi Arabia. Our frontend architecture was built on Svelte microfrontends, with separate apps handling user management, checkout, marketing, and search exploration. Our backend was fully powered by GraphQL, and in the beginning, we adopted Houdini as our GraphQL client. Houdini is a great library, but in practice we found that the generated code often felt unclear and rigid, especially for component-driven queries instead of page-driven queries. This became most noticeable when building smart components—UI elements that need to handle their own API calls, such as: A header showing user login state A shopping cart widget with live updates Shared navigation or marketing components that are reused across apps but still need to…  ( 6 min )

Security is often treated as a late stage gate. In a cloud native world, that's a tax on velocity. Shift Left Security flips the script. We integrate security earlier.

tokencount is a new Rust CLI that helps you answer a deceptively simple question: how many GPT tokens are hidden across this project?

Did you know? Pods can have public IP address and a dedicated security group Recently I was working on deploying telephony systems on AWS EKS, While doing so I realized that running media servers based on RTP (Real-time Transport Protocol) behind a NAT gateway is not a feasible option. For RTP to work both the ends should be able to communicate directly over a Network (Internet / Intranet). image ref An easy solution would be to make an EKS worker node public, open up the security groups, and voila – things would start working. However, this approach comes with a significant security flaw. RTP, by nature, requires a large range of ports to enable concurrent streaming. To achieve this, around 10,000 ports would need to be whitelisted in the security group. If higher concurrency is require…  ( 8 min )

Introduction Imagine you need to double every number in a list of 1000 values. One approach is to take the first number, multiply it by 2, write down the result, then move to the second number, multiply it by 2, write it down, and repeat 998 more times. Another approach is to use a spreadsheet where you can select all 1000 cells at once, apply a "multiply by 2" formula to the entire selection, and watch all results appear simultaneously. The first method processes each number individually. The second handles the whole collection in one operation. This second approach captures the essence of vectorization in machine learning. Most machine learning tasks involve repetitive calculations on large amounts of data. Without vectorization, a program might take several minutes to train a simple m…  ( 12 min )

At the outset of my Dentrix integration I definitely felt like I was pulling teeth. Welcome to this episode of SOAP/ XML nightmares, random auth failures and patient data that disappears. I'll be your host. I thought Open Dental would be straightforward. It wasn't. SOAP/ XML everywhere, auth flows that worked once and broke and appointment slots overlapping.

As software engineers, we’re constantly juggling code reviews, PR descriptions and feedback. Recently I’ve been testing GitHub Models (public preview) — a new feature that lets you prototype, evaluate and use LLMs directly inside your GitHub repositories. One experiment: automatically summarising every Pull Request using a prompt stored as code (.prompt.yml) and a GitHub Action. The Action calls the chosen model (GPT-4o, Claude, Mistral, etc.) and posts a concise summary right back into the PR as a comment. Why it’s exciting: • Prompts & parameters are version-controlled alongside code • Side-by-side model comparisons to balance cost vs. quality • Easy to prototype in the Playground, then integrate in CI/CD This small automation is already making reviews faster and more focused.

How Large Language Models (LLMs) Work: A Complete Overview Large Language Models (LLMs) are a type of artificial intelligence designed to understand, generate, and manipulate human language. They are built on deep learning architectures and trained on massive datasets to perform a wide range of natural language processing (NLP) tasks. Most LLMs are based on the Transformer architecture, introduced in the paper “Attention is All You Need” (Vaswani et al., 2017). The core components are: Encoder: Processes input sequences and generates contextual representations. Decoder: Generates output sequences from these representations. Self-Attention Mechanism: Allows the model to weigh the importance of each word relative to others in a sequence. Feedforward Neural Networks: Apply transformations t…  ( 7 min )

Unconventional Physical Penetration The act of physical penetration extends far beyond the cinematic lockpicking trope. It is a methodical, multi-layered approach that seeks to bypass security by exploiting human behavior, physical vulnerabilities, and the link between physical and digital spaces. These attacks are often non-destructive and aim to compromise security without leaving visible signs of a breach. A foundational method is social engineering, with one common technique being "tailgating," where an attacker follows an authorized person through a secure entrance. This tactic leverages human trust and politeness to bypass access controls. Other methods include "dumpster diving"—sifting through discarded documents for useful information like manuals, invoices, or bank statements—an…  ( 8 min )

If you want people to adopt your AI product, the deployment story has to be as strong as the features. Over the past few decades, the software industry has gone through multiple major transitions. Each one reshaped not only how products are delivered, but also how they are trusted. In the Client-Server Era (circa 2000), apps like SAP and PeopleSoft were purchased and deployed by the customer in their own "on-prem" environment. The customer was in control, but also took on the operational complexity of everything from procuring and deploying hardware to the system software and the apps themselves. In the SaaS Era (circa 2010s), apps such as Salesforce and Workday ran in the provider's cloud and were delivered through the browser. While this simplified operations for the customer, it also me…  ( 8 min )

Shell dot command If you are in middle of a sqlite shell session, and you don't want to quit the shell to run arbitrary shell command, you can simply use the .shell to execute any shell commands right from within the sqlite shell.

WSL and Docker Desktop don't store files directly in NTFS - they live inside giant .vhdx virtual disks. What's more, when you delete stuff inside Ubuntu/Docker the space is freed inside ext4 but the .vhdx file doesn't shrink; it only ever grows. Over time, that leads to those hundreds of gigs just locked up in AppData. …  ( 7 min )

I'm in an odd position because developing something in the open generally means developers at least are part of the target userbase, but my end user for Ephem, a Python CLI for casting and storing horoscopes, is me: a professional astrologer and desktop Linux user who lives in the terminal. There has to be at least one more of us, or an astrologer on macOS who can be swayed to install something with pipx, so I set out to write a tutorial for my CLI tool beyond a simple README to finally ship with v2.0.0 and quickly realized the user I was neglecting the whole time was me. I caught five UX issues in one evening of writing documentation that went unnoticed with weeks of automated tests. Of course I'm a few semantic versions into this development life cycle, but I felt like I was doing somet…  ( 10 min )

Everyday something exciting comes up in machine learning. A new RL technique, a transformer architecture that is 0.001% more effective than GPT-2, synthetic data creation to train neural nets, and whatnot. But before diving into all these things, we must fondly remember the simpler, time tested, arguably more efficient algorithm for less complex problems, ladies and gentlemen, I'M TALKING ABOUT NONE OTHER THAN Yes, you heard me right, I'm going to show you the power of linear regression. If I had to put it in a single sentence, linear regression is a machine learning model that tries to find a linear equation f(x) = y = ax + b that fits our data the best. It's not all sunshine and rainbows though, as we run into our first major issue. How do we define "fitting our data the best"? We have…  ( 8 min )

In the past year, we have not heard about generative AI, without hearing terms such as agentic AI, AI agents, MCP, and recently A2A protocol. When building agentic AI systems (whether using a single AI agent or multiple agents communicating with each other autonomously), as technology is still evolving, we should be aware of security threats, design accordingly, and embed security controls to mitigate against potential risks. Agentic AI differs from generative AI in that it acts autonomously to carry out complex, multi-step tasks toward a goal with minimal human direction, whereas generative AI responds to specific prompts by creating content like text or images but stops there; however, this autonomy introduces new security risks such as agents being manipulated through prompt injection…  ( 15 min )

I always thought healing would feel like light: soft, gentle, almost like the scene at the end of a film where the character breathes easy, finally free. But when I started healing, it didn’t feel anything like that. It felt like fire. It felt like my chest was a furnace that had been locked for years, and the moment I cracked it open, every suppressed ember leapt out. I wasn’t peaceful. I was angry. Furious, even. At first, I thought something was wrong with me. Who gets mad while trying to heal? Shouldn’t healing feel like forgiveness, serenity, acceptance? But the thing is, before I found any peace, I found rage. I was angry at the people who had hurt me, at the years I’d lost, at the version of myself who had swallowed her voice to survive. It came out in unexpected ways. I snapped at …  ( 8 min )

Your latest deployment just failed. A critical vulnerability in an outdated library brought production down. Sounds familiar? Modern applications rely on hundreds of dependencies, each representing a potential security risk.

Zero Trust Architecture = A security model where no user or device is trusted by default, whether inside or outside the network, and access is given only after continuous verification. Zero Trust = “Never trust, always verify” 🏗️ Core Principles of Zero Trust Architecture Verify Explicitly – Authenticate and authorize based on user identity, device, location, app, and risk. Use Least Privilege Access – Give users the minimum required access, with Just-in-Time (JIT) and Just-Enough-Access (JEA). Assume Breach – Always monitor, log, and segment networks to contain damage if attackers get in. 📌 How Your List Maps to Zero Trust Pillars Identity → Strong Identity Control (Entra ID, MFA, PIM) Devices → Device Compliance (Intune, Defender for Endpoint) Access → Adaptive Conditional Access Network → Segmentation & Edge Protection (Azure Firewall, NSGs, WAF) Applications → Runtime & App Controls (Defender for Cloud Apps, GitHub Security) Data → Data Protection (Purview, Encryption, Priva) Monitoring → Continuous Threat Detection (Sentinel, Secure Score) Infrastructure → Hardening (Arc, Managed Identities, Private Endpoints) APIs → API & Private Connectivity (Defender for APIs, APIM) Governance → Telemetry & Compliance (Secure Score, JIT Access, Audit) Zero Trust is no longer optional—it’s the backbone of modern cloud security. Microsoft’s security ecosystem (Entra ID, Intune, Sentinel, Defender, Purview, etc.), organizations can build a resilient security posture that protects identity, data, applications, and infrastructure end-to-end.  ( 6 min )

TL;DR Summary The typical cost to build a custom React/Next.js web app in 2025 varies significantly based on complexity and team choice. Freelancers usually charge between $5,000 and $25,000 for MVP-level projects, while agencies typically start around $20,000, scaling up to $200,000+ for feature-rich or enterprise applications. Founders often find it challenging to estimate the cost and timeline for custom web app development due to multiple factors: Diverse project complexities (from simple MVPs to enterprise platforms). Varying hourly rates across freelancers, agencies, and geographic locations. Impact of technology choices and third-party integrations. Scope creep and shifting priorities during development. These factors create ambiguity, leading to unclear budgeting and unrealistic …  ( 6 min )

Building an email OTP node in ForgeRock AM is a crucial step in ensuring secure authentication for your users. HOTP is a widely-used algorithm that generates a unique password for each login attempt, providing an additional layer of security. In this example, we'll demonstrate how to create an email OTP node using HOTP and configure email sending with ForgeRock AM. First, create a new node in your ForgeRock AM instance and select "Email OTP" as the node type. Then, configure the HOTP settings, including the algorithm, key size, and iteration count. Next, set up the email sending configuration by specifying the email server details and the subject and body templates for the OTP email. Once the node is created and configured, test it by sending an OTP email to a test user. In the email, you should receive a unique password that can be used for login.

When I first read the now famous tweet from Joanna Maciejewska I want AI to do my laundry and dishes so that I can do art and writing, not for AI to do my art and writing so that I can do my laundry and dishes. I could not agree more. I love writing code and I do not want AI to take over what I enjoy so much. But I would like AI to do the boring stuff that is part of a developer’s day-to-day life. If you know me, then you probably know that I like to keep the number of meetings to a bare minimum, and I do not like spending a lot of time on triage, planning, and retrospectives.

🔹 Lazy Loading in ElastiCache Lazy loading is a caching pattern where data is loaded into the cache only when it is requested for the first time. Here’s how it works in Amazon ElastiCache (Redis or Memcached): App requests data → Check cache first. If data is in cache (cache hit) → return it immediately. If data is NOT in cache (cache miss) → Fetch it from the database (or another backend). Store it in the cache for next time. Return it to the application. Imagine you’re caching user profiles in ElastiCache Redis. Request for user:123 profile → not in cache → app queries RDS MySQL → stores result in Redis → returns profile. Next request for user:123 → found in Redis (cache hit) → super fast, no DB query. ✅ Pros Easy to implement. Reduces DB load after first access. Data is only cached i…  ( 7 min )

Given the advantages of declarative desired state and the tools that reconcile it, why aren’t organizations adopting it faster? Declarative desired state is the GitOps principle everyone knows but few actually use. The recent State of GitOps report found that just 40% of organizations were using declarative configuration, so what is it and why is it so fundamental to successful GitOps? There are two ways to manage state in GitOps. The first is to define a sequence of steps to take a baseline and move it into the desired state. This checklist-style approach is imperative: a set of step-by-step instructions reach the intended outcome. In contrast, declarative state defines the end state, not the steps to reach it. We can think of this in terms of pizza. You can follow the recipe by stretchin…  ( 8 min )

https://nrc.tarushnagpal.com Nike’s Run Club (NRC) app is beloved by runners for its Audio-Guided Runs, where top coaches (and even stars like Eliud Kipchoge) talk you through workouts. These runs cover everything from easy jogs to tough speed sessions. The NRC app now has hundreds of them (306 to be exact), but frustratingly, there’s no built-in search or filter. Most runners end up endlessly scrolling just to find the one they want. Here are just a few examples of people complaining (and there are many more): So I built NRC Run Search to solve exactly this. The site lets you: Search by keyword: Type any word from a run’s title or description (e.g. “tempo”, “Bennet”, “intervals”) and instantly filter the library. Because Nike’s coaches have already prepared amazing guided workouts, we’re just making them easier to find. There were two main problems while building this: I didn’t want to manually build the dataset by clicking on each run, copying the info, and cleaning it up. The share link in the app kept changing every time I clicked it, and it wasn’t tied to the run’s actual ID. I used HTTP Toolkit to set up an HTTP proxy. This let me route my iPhone traffic through the proxy running on my laptop (same Wi-Fi). And voilà — all the app’s requests showed up in the proxy! From there, I just copied the contents of each request. (Sure, I could’ve scripted it, but honestly, it was only ~12 pages, so this worked fine.) The dataset now lives in my open-source app here: GitHub link. Remember the rotating link issue? Turns out NRC uses singular.net to generate deep link URLs — probably for shortening + tracking (seems a bit overkill). The good news: the payload of that call already contained the actual deep link to the app. Here’s the code that generates the deep link. And that’s it — both problems solved, which gave us nrc.tarushnagpal.com.  ( 6 min )

It gets more weird when you realise back then I did not know anything about programming languages!

If you don't know what it is, look at the following example: normal_way = [ 'item1', 'item2', 'item3' ] # now let's write it with comma-first comma_first_way = [ 'item1' , 'item2' , 'item3' ] As you see in the example above, in comma-first, instead of ending a line with a comma, we start the next line with a comma!

As many other students I had to write my Bachelor thesis in Latex. So I had to choose between Overleaf, the complete integrated tool for Latex work, or setting up some local writing environment myself. As I wanted to have full control over my setup and sync my work across multiple devices using Git (which is also available in a paid subscription of Overleaf), and I also kinda hate myself a bit, I decided to go with the local setup. As the work was growing more and more in terms of pages and the compilation got slower and slower, I had to think of some ways to improve and optimize the build process to make it more comfortable for me. The general suggestion is to use as much precompilation as possible to avoid double compilation and therefore significantly speed up the document build process…  ( 15 min )

The rapid evolution of AI agents has opened up new paradigms for productivity, enabling a single conversational interface to interact with a multitude of data sources and applications. A core component of this shift is the Model Context Protocol (MCP)1, an open standard for defining and exposing tools, such as those for calendar management, email, or CRM, to large language models (LLMs). While highly transformative, the practical deployment of MCPs in an organizational setting presents significant challenges related to security, compliance, and user management.

Imagine we have an expensive parseAppRoute function that performs many effects. We do not want it to run twice: once for Navigate and again for UrlChanged. (I am ignoring LinkClicked in this explanation, since in my app I only use Navigate, but the principle is the same.)

Not exactly the kind of surprise you want in your logs, especially when regulators (and your security team) are watching.

Recently, I have been working on a small side project that involves creating a command-line interface for the ecosyste.ms platform. We had started to investigate different sources of metadata for purl-patrol and stumbled over ecosyste.ms. If you've never heard of ecosyste.ms, it's essentially a huge dataset about open source software that keeps track of repositories, packages, dependencies, and other fascinating metadata throughout the whole open source ecosystem. The problem is that even though ecosyste.ms has some fantastic web APIs, I was always wanting to use the terminal to query them—for example, in a pipeline or build script. You understand that there are instances when you simply want to verify something quickly without launching a browser or creating a custom script. ## Why Crea…  ( 8 min )

Introduction In the age of smartphones, mobile photography has transformed into an essential part of our digital lives. For many, editing is no longer optional — it’s an art form. Adobe Lightroom is among the most widely used apps for photo editing, offering tools like color grading, presets, and object removal. But here’s the catch: many of Lightroom’s advanced features are locked behind a subscription. This paywall has led to the rise of Lightroom Mod APK, a modified version that unlocks premium features for free. On the surface, it looks appealing. But as developers and creators, we need to carefully consider what it means to use modded software. Let’s break it down. What is Lightroom Mod APK? Lightroom Mod APK is an unofficial variant of Adobe’s Lightroom app. It is created by modifyin…  ( 8 min )

React has emerged as a dominant force in the landscape of frontend development, often seen as the go-to library for building user interfaces. Its extensive ecosystem, robust community support, and continuous updates have led many developers to adopt it as their primary tool for web application development. However, this overwhelming adoption comes with a paradox: while React is winning by default, its status may be inadvertently stifling innovation. In this post, we'll explore the implications of React's dominance, examining how it shapes current development practices, impacts performance, and influences the evolution of new frameworks and tools within the broader JavaScript ecosystem. React's climb to the top of the frontend stack can be attributed to several factors. Its component-based …  ( 8 min )

AI is a high-cost, high-impact capability. Its value comes not from novelty, but from how effectively it addresses genuine user needs and drives measurable business results. “Let strategy set the direction, and technology follow”—ensure business objectives lead, with AI as an enabler, not the driver. Too often, teams start with AI because it’s exciting, not because it addresses a clear need. This leads to wasted effort, high costs, and little user impact. Instead, begin with a hypothesis about user impact, use the smallest effective AI, and measure results. Start with the user problem: What specific friction or failure are you trying to address? For whom does it matter most? Define success up front: Choose a single primary metric that will prove if the AI feature works. Know your baseline …  ( 7 min )

What is Private Google Access? Private Google Access (PGA) is a GCP feature that allows Virtual Machine (VM) instances without external IP addresses to access Google APIs and services (like Cloud Storage, Cloud Run, Pub/Sub, etc.) through internal IPs only. This helps keep workloads private while still interacting with Google services. Key Points: Configured per subnet (ON/OFF). Only affects VMs without external IPs. VMs with external IPs are unaffected—they can access Google services normally. Project: gcpdemos VPC: vpc2-custom Contains two subnets in the us-central1 region: mysubnet1 (Private Google Access: OFF) mysubnet2pga (Private Google Access: ON) VM1 Subnet: mysubnet1 (PGA OFF) Private IP: 10.225.0.5 No external IP Cannot access Google APIs internally. The diagram shows a red cross indicating blocked access. VM2 Subnet: mysubnet2pga (PGA ON) Private IP: 10.131.0.5 No external IP Can access Google APIs internally (shown with a blue arrow connecting to Cloud Run). Service is internal-only. VM2 can communicate with it via Private Google Access. VM1 cannot communicate because PGA is disabled in its subnet. Subnet-level control: Enable PGA at the subnet level to allow private VMs access to Google services. Security-first approach: VMs can remain without external IPs, reducing exposure. Simple connectivity: Eliminates the need for NAT or external IPs just to access Google APIs.  ( 6 min )

When working with interactive maps, two concepts sit at the foundation: zoom levels and tiles. Without them, platforms like Google Maps, Leaflet, or MapLibre GL would be impossible. Instead of loading one massive image, modern maps are composed of tiles — small 256×256 px squares that fit together in a grid. As you zoom in, the number of tiles grows exponentially, providing more detail at higher levels. At zoom level 0, the entire world fits into a single tile. At zoom 1, the map splits into 2×2 tiles (4 total). At zoom 2, it’s 4×4 (16 total). In general, zoom level z produces a grid of 2^z × 2^z tiles. These tiles are addressed using the XYZ scheme ({z}/{x}/{y}), where z is the zoom, and x and y are the column and row numbers in the grid. In this article, we’ll explore how zoom levels wor…  ( 10 min )

Short links are everywhere. They make it easier to share content, but most existing URL shorteners are built for individuals, not for teams or companies. That’s why I built Linanok. Linanok is an open source, self-hosted URL shortener designed specifically for organizations that need professional link management. Instead of relying on third-party services, teams can keep full control over their data while still enjoying a smooth and modern experience. Most URL shorteners stop at creating and tracking links. Linanok goes further by focusing on staff-level link management. Organizations can create roles, assign permissions, and make sure every team member has the right level of access. This helps maintain security and order, especially when multiple departments or users are working with links. Linanok is built with Laravel and Filament, which makes it robust, extensible, and easy to manage. The default database is PostgreSQL, but it also supports MariaDB and SQLite, giving teams flexibility depending on their infrastructure. Staff-level link management: manage links per user with clear permissions Analytics: track clicks and see where your visitors come from Role-based access control: keep security tight with customizable roles Open source and self-hosted: run it on your own infrastructure under the MIT license Linanok is available in two ways: Self-hosted: deploy it on your own infrastructure and keep full control SaaS: use the hosted version and get started instantly, no server setup required This flexibility means teams can choose the model that best fits their workflow. Linanok is built for businesses, organizations, and teams that need to share short, branded links without losing control of their data. If you want to keep things in-house while still providing your staff with a professional tool, this is for you. Linanok is now available at https://linanok.com. You’ll find installation instructions, documentation, and the source code. I’d love to hear your feedback and ideas to make Linanok even better.  ( 6 min )

At its core, SVM is a data classification method that separates data points into categories using hyperplanes. While the concept may sound technical, it is both intuitive and practical once broken down. This blog explains how SVM works, how to implement it in R, how to tune models for better accuracy, and how SVM compares with other methods like linear regression. Understanding the Basics of SVM The main idea behind SVM is to separate data points into different classes using a line, plane, or hyperplane. In two dimensions, this separator is a straight line. In three dimensions, it becomes a plane. For data with higher dimensions, the separating surface is called a hyperplane. SVM’s uniqueness lies in the fact that it does not simply look for any separating line but instead seeks the most o…  ( 10 min )

Traditional web3 mining once required expensive hardware, loud cooling fans, and high electricity bills. Neurolov introduces a new model: instead of mining arbitrary blocks, everyday devices can contribute idle compute power to real AI workloads directly through the browser. This article explores how Neurolov’s NeuroSwarm turns laptops, desktops, and even mobile devices into contributors for a decentralized GPU compute network. In the Web3 ecosystem, the concept of “mining” is evolving into something broader: device monetization through real utility. Old model: solve arbitrary puzzles (Proof-of-Work) → high energy use, limited application. New model: process real AI tasks (image generation, LLM inference, video rendering) → immediate value for developers and researchers. Neurolov’s …  ( 7 min )

1. What is Spring Framework & Spring Boot? Spring Framework is a Java framework that provides infrastructure support for building enterprise-level applications. Its biggest feature is Inversion of Control (IoC): instead of you creating and wiring objects yourself (new SomeClass()), Spring creates and manages objects (beans) for you, injecting them where needed. Spring Boot is a tool built on top of Spring Framework that makes development much faster by: Auto-configuring things (no XML configs anymore). Providing “starter” dependencies (just add one line in pom.xml instead of 10). Embedding Tomcat/Jetty so you can run apps with just java -jar. Without Spring Boot, you’d need to manually configure database connections, servlet containers, and beans. With Spring Boot, it’s mostly automa…  ( 8 min )

Imagine this: your app is scaling beautifully, millions of requests per day, and everything looks perfect… until one day, your distributed cache crashes. Suddenly, the entire system grinds to a halt. Users are refreshing like crazy, servers are choking, and the cache—the very thing designed to prevent bottlenecks—has become the single point of failure. Sounds scary? It is. And it’s happening more often than you think. Distributed caches like Redis, Memcached, or Hazelcast are often seen as the magic bullet for performance. They: Reduce database load Speed up responses Keep your system scalable But here’s the catch: if the cache cluster goes down, your entire system may crumble. Instead of being your safety net, the cache becomes the biggest weak link. Think of a login service. Every time …  ( 7 min )

Interviewer: “How are you going to handle cross-browser compatibility in this project?” This is one of those classic interview questions where most developers tend to give fairly predictable answers. These are valid points, but they lean heavily on manual effort and can sometimes sound too generic. My answer, given that Tailwind CSS is required for the project: Preflight (Tailwind’s reset layer): Autoprefixer (via PostCSS): Standards-First Utilities: Future-Friendly: Verification Step (Best Practice): Why this answer stands out in an interview Instead of saying “I’ll test and fix issues as they come”, I tie my solution directly to the tooling required in the project (Tailwind CSS). This shows I understand how Tailwind doesn’t just speed up styling, but also solves deeper engineering challenges like cross-browser compatibility out of the box. In other words, I’m not just giving a generic answer — I’m giving a framework-aware answer.  ( 7 min )

So, I was chatting with a friend about why we keep going back to certain websites or apps, and it hit me – it’s not always the product itself, but how it feels to use it. That’s where UI/UX design sneaks in. From my own experience: If the navigation is smooth, I don’t get frustrated and just… stay longer. When things load quickly and the flow feels natural, I’m way more likely to come back. Even small touches, like helpful micro-copy or a clean checkout process, make me trust the brand more. Honestly, a confusing layout or clunky design can push me away faster than bad pricing sometimes 😅.

A missed period is a source of stress for a woman especially when conceiving is under consideration. Most women opt for a home pregnancy test kit, commonly known as the UPT test, to verify the pregnancy. UPT tests are easily available over-the-counter; they function by detecting the level of pregnancy hormone, hCG (human chorionic gonadotropin), present in the urine.Well, what about an occurrence of a missed period with a negative result in the UPT? At Dr. Aravind's IVF, we frequently meet patients for whom this is an issue, and the understanding of the science behind it is important. Concept of a UPT Test The UPT test is an easy method to detect pregnancy in its early weeks by measuring levels of hCG in urine.

In the last few years, the way people consume entertainment has completely changed. Instead of relying only on television, millions of users now prefer streaming content directly on their mobile devices. This shift is happening because smartphones have become more powerful, data packages are cheaper, and people want entertainment on the go. Another big reason behind this growth is the variety of apps available for different needs. Some platforms focus on sports, while others specialize in movies, anime, or even live TV channels. Users can explore global content without being tied to a specific location. At the same time, developers are working on making these apps more secure and user-friendly. Features like offline downloads, multiple language support, and personalized recommendations have made streaming even more attractive. The result is a highly competitive market where only the best apps survive. It is clear that mobile streaming is not just a trend — it is the future of entertainment. From casual viewers to passionate fans, everyone can find an app that matches their interests. As technology continues to improve, we can expect even smoother, smarter, and more interactive streaming experiences.  ( 6 min )

Intro The internet is full of articles on CEOs declaring their companies "AI-first", in the name of increasing efficiency. After all, why have 50 engineers if you can have 5 managing a swarm of AI agents? I am a heavy user of GenAI assistive tools and they truly do help me achieve results faster. But another thing that helps you achieve results faster is not having to fight an uphill battle against whichever text editor you're using. If you have to lift your hands from the keyboard, you're wasting time. Yet I never heard any company issuing a "Vim keybindings mandate" and declaring themselves "modal-editing first", even though these tools are over 30 years old. If we squint hard enough, defining programming is very simple -- we solve problems by translating abstract processes into textua…  ( 8 min )

While working through my DevOps journey (Week 13), I deployed a Node.js app to AWS EC2 and compared single-stage vs multi-stage Docker builds. Here’s what I learned 👇 🐳 Simple Dockerfile Uses a full Node.js base image. Includes build tools + dependencies. Final size: 1.2GB. ⚡ Multi-Stage Dockerfile Build stage: compiles and prepares app. Run stage: copies only the essentials. Base: distroless image. Final size: 3MB 😍. Why This Matters in DevOps Production environments need lightweight images. Faster push/pull → smoother CI/CD pipelines. Lower resource usage on servers. More secure (no unnecessary OS packages). 🔗 Check out my implementation here: GitHub Repo 🌐 See more about me: https://azmatahmed.netlify.app Keywords: Docker, Multi-stage builds, Node.js Dockerfile, AWS EC2, Distroless images, DevOps best practices, Optimize Docker images, DevOps learning.  ( 6 min )

Async Function Returning a Boolean — A Practical Example 💡Intro Theory is boring. Let’s check something real: is a user logged in? That’s a simple Boolean but in modern apps, it’s often async. Sync version works if the info is instantly available. But in practice, you check from a server or token → async. Examples // Synchronous function isUserLoggedIn(): boolean { return true; } // Async async function isUserLoggedIn(): Promise { const response = await fetch("/api/check-login"); const data = await response.json(); return data.loggedIn; } // Arrow version const isUserLoggedIn = async (): Promise => { const response = await fetch("/api/check-login"); const data = await response.json(); return data.loggedIn; }; Login checks in apps like Gmail, Slack, or banking dashboards, always asyncbecause they rely on tokens or API calls. Even if you currently return true, keeping the function async future-proofs your code when you switch to an API.  ( 6 min )

Modern computing systems are built with multiple cores, large amounts of RAM, and often access to cloud clusters. If your R code still runs serially for tasks that could benefit from parallelism, you’re leaving performance on the table. Parallel processing isn’t just a technical trick—it’s essential for scaling data workflows, reducing wait times, improving productivity, and enabling more complex analyses. This article walks through how to implement parallel processing in R effectively in 2025: tools, practices, pitfalls, and how to incorporate parallelism without sacrificing reliability and reproducibility.

Next.js has always been at the forefront of modern web development, offering developers powerful rendering strategies like SSG (Static Site Generation), SSR (Server-Side Rendering), and ISR (Incremental Static Regeneration). But with Next.js 15, we now have a new approach: Partial Pre-Rendering (PPR). PPR bridges the gap between static and dynamic rendering, providing the best of both worlds—blazing fast page loads while keeping content fresh and interactive. Partial Pre-Rendering (PPR) allows Next.js to pre-render the static shell of a page (like layout, header, footer, navigation) at build time, while streaming dynamic parts (like personalized dashboards, product stock, or user-specific data) directly from the server. This means: Static content = 🚀 Lightning fast (cached & CDN-ready) Dy…  ( 7 min )

Silence can feel heavier than words. In conversations, especially as a leader, there's an instinct to fill every gap, to keep things moving, to show that you're engaged. But I've learned the most valuable moments often come when I do the opposite-when I leave the space open. In my 1:1s, I try to pause before responding. It's not about waiting for my turn to speak, but about listening to understand, not just to reply. Sometimes that pause encourages the other person to keep talking, to elaborate in ways they might not have if I'd jumped in too quickly. Other times, it gives me the clarity to respond more thoughtfully-or even the courage to admit I need time before giving an answer. When I first joined Loop, someone pointed out that I had a habit of filling silence. Luckily, I caught that before I started running 1:1s with my team. Those meetings aren't meant for my voice to dominate. They're their time, their space. My role is to hold it, not to crowd it. As for interpreting silence, context matters. In deeper conversations-whether about growth, progression, or tough questions-silence usually means thought. It's the weight of someone considering their words, reflecting before speaking. I haven't yet experienced it as something negative. More often, it's the quiet before honesty. Silence doesn't need to be awkward. It can be an ally. The courage lies in resisting the urge to break it, and instead trusting what it makes possible. Next time: When Not Having the Answer Is the Answer  ( 6 min )

JavaScript Comparison: Mastering the Art of Equality Hey there, fellow developers! If you’ve spent any time at all writing code, you know that the ability to compare things is the bedrock of programming. It's how we make decisions, control the flow of our programs, and build intelligent applications. Is a user logged in? Is a form field empty? Is this a valid password? All these questions are answered with comparison. In JavaScript, this seemingly simple concept can quickly become a source of confusion, frustration, and a whole lot of bugs. The culprit? The infamous difference between the double-equals (==) and triple-equals (===) operators. For a beginner, this is a head-scratcher. For an experienced developer, it’s a constant reminder of JavaScript's unique and sometimes quirky nature.…  ( 13 min )

Mastering JavaScript Booleans: The Bedrock of Logic and Decision Making Imagine trying to build a house without a foundation, or a car without an engine. You might have the walls and the wheels, but nothing would function. In the world of JavaScript programming, Booleans are that fundamental engine. They are the simple, powerful true and false values that drive every decision your code makes, from showing a "Login Successful" message to filtering a list of products or validating a form. While the concept seems elementary, a deep and nuanced understanding of Booleans—and their quirky companions, "truthy" and "falsy" values—is what separates novice scripters from professional developers.

Your Java application has memory issues: maybe it’s throwing OutOfMemoryErrors, or maybe you’re experiencing degraded performance or frequent timeouts. You suspect a memory leak, and your heap dump analyzer has identified a few leak suspects in the Java heap space. In this article we’ll look at some typical coding issues that result in memory leaks, and how to find and fix the problem. A memory leak occurs when a program unnecessarily allocates more and more memory over time. Eventually, the program slows down and finally throws an OutOfMemoryError. Not all memory problems are leaks: they could be caused by either wasted memory, under-configuring the heap or other memory pools, or lack of RAM in the device or container. The best way to tell if the problem is a memory leak is to analyze the…  ( 9 min )

Preparing for a cloud certification is often a solo journey. your WHY Why do you really want this certification? ➡️ A new job opportunity? ➡️ Building new skills? ➡️ Personal challenge? If your only reason is “because my colleague just passed it,” you’ll probably lose steam quickly. A strong WHY is what will keep you moving when motivation dips. Saying “I’ll pass this exam this year” is too vague. I’ve seen people repeat it for 3 years in a row. Instead, be specific: “I’ll pass this exam within 3 months — before November 30.” Personally, I love buying exam vouchers that expire soon. It forces me to stay disciplined. Sometimes it’s not you—it’s the material you’re using. There are tons of courses out there, but the key is to pick the right ones. A well-structured, hands-on course makes it much easier to stay consistent. 🎯 My advice: stick to 2–3 solid resources max. More than that, and you’ll just lose focus.

📌Intro You write a simple asyncfunction, return 42, and suddenly TypeScript yells: “Type 'number' is not assignable to type 'Promise'.” The asynckeyword in TypeScript (and JavaScript) changes how the function behaves: Every asyncfunction always returns aPromise. Even if you return a raw value, it’s wrapped in Promise.resolve(value). Examples: // Normal function function getFavoriteNumber(): number { return 26; } // Async function async function getFavoriteNumber(): Promise { return 26; // Actually Promise.resolve(26) } // Arrow version const getFavoriteNumber = async (): Promise => { return 26; }; If you try: async function getFavoriteNumber(): number { return 26; } TypeScript error: Type 'number' is not assignable to type 'Promise'. Real-Life Example: You might start with a hardcoded value, but later fetch it from an API. Making it async upfront saves refactoring: const getFavoriteNumber = async (): Promise => { const res = await fetch("/api/fav-number"); const data = await res.json(); return data.number; }; 💡Think of asyncas a “Promise factory.” Whatever you return gets gift-wrapped in a Promise.  ( 6 min )

A mix of fun and surprising facts about Git Created by Linus Torvalds in 2005 — the same person who created Linux. He jokingly called it “Git” because in British slang it means an unpleasant person, poking fun at himself. Linus created Git in just two weeks after a licensing dispute with BitKeeper (the system the Linux kernel used before Git). Git was designed to be blazingly fast — a key reason Linus wrote it himself. It’s optimized for branching and merging — something that was painful in other systems at the time. Git stores snapshots, not differences — making operations like checking out, reverting, and branching faster and more reliable. Everything in Git is identified by a SHA-1 hash (40-character string). This makes it extremely reliable for detecting corruption or tampering. A Git repository is essentially a key-value data store — branches, commits, and tags are just pointers to objects. Git’s .git folder contains the entire repository history. If you copy just that folder, you’ve copied the repo. Git is now the most widely used version control system in the world, powering GitHub, GitLab, Bitbucket, and countless self-hosted servers. GitHub started in 2008, only three years after Git was created. The largest public Git repo (by number of commits and size) changes often, but projects like the Linux kernel remain massive showcases of Git’s scalability. You can create branches with emoji names 🐱‍👤. The command git reflog is like a time machine — you can recover commits you thought were lost. Git’s “plumbing” commands (like git cat-file and git rev-parse) let you peek deep inside the repo and treat it like a database. Git popularized concepts like pull requests (thanks to GitHub’s interface). Its distributed model means you can have a complete copy of a project offline — very different from older centralized systems like Subversion (SVN). Git has inspired non-software uses, such as tracking research papers, books, legal documents, and even recipes.  ( 6 min )

“Wait… is this price in dollars or euros?” Now imagine this: Sarah, a buyer from London, adds a jacket to her cart for $100. She assumes it’s in British pounds (£). But at checkout, she’s shocked—the price converts into £80 plus unexpected fees. Frustrated, she abandons her cart. This is a story repeated across the globe, and it highlights a critical truth: currency and date formatting are not “small details”—they are trust signals that directly impact conversion rates. In today’s global digital marketplace, businesses that ignore localization risk losing sales, while those that adapt win customer trust and loyalty.

Overview Introduction to MCP MCP “Tool Poisoning” Attack The tool poisoning attack is a covert attack method implemented through the Model Control Protocol (MCP). Its core feature is to embed malicious instructions that are invisible to users but visible to AI models in tool descriptions. Attackers use AI models to parse the features of complete tool descriptions and implant hidden instructions (for example, marked with special tags) in the tool function description to induce the model to perform unauthorized operations. For example, you can directly access sensitive files (such as SSH keys, configuration files, and databases). Attack Principle ● Semantic parsing: The large model prompts the host to use a file-reading tool to read the SSH private key file (~/.ssh/id_rsa). ● Host reads th…  ( 19 min )

Introduction In today’s digital-first world, a customer rarely makes a purchase decision after just one interaction. Instead, they typically pass through several touchpoints before completing a purchase—something especially common in e-commerce. Fortunately, these touchpoints are easier to track than ever. As marketing becomes increasingly consumer-centric, understanding which channels influence conversions has become crucial. By identifying the right channels, companies can allocate budgets effectively and engage customers in the right place at the right time. However, businesses often focus disproportionately on the final channel before conversion, overlooking earlier interactions that play an equally important role. To capture this broader perspective, marketers rely on multi-channel at…  ( 8 min )

And like most developers here, I ended up building my way out. I’ve always wanted to speak Spanish… but more than speaking, I wanted to understand it. I listen to reggaetón all the time, so I wasn’t starting from zero. But when a Bad Bunny song comes on, I wanted to feel the lyrics, not just hum along. Enter Duolingo — the gateway drug for Spanish learners. I got hooked. In the beginning, it was fun. The gamification worked. My streak climbed. My vocabulary grew. But then the fear of losing the streak took over. Learning turned into an obligation. Fast forward: I’m at a Bad Bunny concert in San Juan. The vibe was next level — but I only understood maybe half of what he was saying. I know the Puerto Rican accent is difficult but still six months of Duolingo everyday, and I still couldn't ca…  ( 7 min )

AWS finally updated AWS console to allow differentiating the AWS accounts by colour. Oh! what do I mean. Well, if you work in cloud environments, you probably work with multiple AWS accounts. More often than not, the accounts are setup for development, test, production and other types of environments. Most companies will have separate accounts for different environments. With options to login to multiple accounts, it is always a pain to know which account I have logged in to. Yes, you can see the AWS account on the top right, but who remembers the account id, right. I am still waiting to see the account name somewhere to easily identify the account. Well, until that happens, AWS recently released an option called AWS User Experience Customization (UXC) that lets you set the colour of the a…  ( 7 min )

In a cloud-native environment, the Shared Responsibility Model for code security outlines the division of security duties between a cloud service provider (CSP) and the customer. The model dictates that the CSP is responsible for the security of the cloud, while the customer is responsible for security in the cloud. CSP Responsibility (Security of the Cloud): The CSP is responsible for the security of the underlying infrastructure on which the customer's code runs. This includes the physical servers, storage, networking hardware, and the virtualization layer. For managed services like AWS Lambda, the CSP secures the underlying operating system and the serverless execution environment itself. Customer Responsibility (Security in the Cloud): The customer is solely responsible for the security of their own code. This includes securing the application code from vulnerabilities, ensuring proper access control, and managing sensitive data and secrets. This responsibility extends to the open-source components, third-party libraries, and APIs used in the code. Security tools like Static Application Security Testing (SAST) and Software Composition Analysis (SCA) fall squarely under the customer's purview. By understanding this division, a customer can build a comprehensive security program that focuses on what's their responsibility, leveraging the security provided by the CSP to build a more resilient application.  ( 6 min )

Ever wanted to log real-time sensor data with your Arduino? So what’s the solution? In this guide, we’ll walk you through how to interface a Micro SD card module with Arduino step by step. A Micro SD card module is more than just a card slot. It includes: Micro SD Card Socket – Where you insert the card. Most modules have clear markings to avoid wrong insertion. 3.3V LDO Voltage Regulator – Since SD cards work at 3.3V, the regulator safely steps down Arduino’s 5V to 3.3V. This prevents damage while keeping voltage stable. Logic Level Shifter (74LVC125A) – Acts as a translator that converts Arduino’s 5V logic signals to 3.3V for the SD card, ensuring safe and reliable communication. Micro SD Card Module Pinout Here’s the pin configuration you’ll use while wiring it with Arduino: GND → Con…  ( 9 min )

Laravel Policies are a powerful feature for managing authorization logic in a clean, reusable way. They allow developers to define access control rules for specific models, keeping authorization logic separate from controllers and views. But are they really used in real-world projects, or are they just a shiny feature that sounds good on paper? Let’s dive into their practical use, benefits, and when you might skip them. Policies in Laravel are classes that organize authorization logic for a specific model or resource. They’re typically used with Laravel’s Gate or the authorize() method to control access to actions like viewing, creating, updating, or deleting resources. For example, a PostPolicy might define who can edit or delete a blog post. namespace App\Policies; use App\Models\Post;…  ( 8 min )

Popular ML runtime frameworks include ExecuTorch, ONNX runtime, TensoRT. They bridge the gap between model training and model deployment. ML models are usually trained with PyTorch on a GPU. But directly deploying them in PyTorch format is cumbersome. PyTorch’s inference runtime libtorch is written in C++ and very heavy. Other ML runtime like ExecuTorch, also coming from the same PyTorch team, is built for embedded environment with lightweight and efficiency as its primary goals. ML runtime is created to be deployed on different hardware backends, GPUs, NPUs, TPUs, CPUs, DSPs and other accelerators. So that models can be delivered in one single format (a DAG graph that describes the relationship between tensors and operations, as well as a binary of weights) and deployed on many different platforms.  ( 6 min )

For the longest time, I thought generating XML reports from Pytest was just… annoying. Run tests with -n for parallel workers → I’d get 4 different XML files or more with increasing number of tests. Retry a flaky test → extra XMLs scattered around. Then I’d have to either write my own merge script or dig up some plugin to stitch them back together.(Not to mention the xml paths relative and absolute and file not found stuff or generating the blobs) Finally, I’d spend time debugging why my CI job wasn’t uploading the “right” XML to TestRail. All of this felt like extra work just to give my test management tool a single file and devops guys who are already loaded and this would be a P3 for them to look at. While searching for something that would automatically generate and merge, I stumbled upon this underrated tool called pytest-html-plus, and I was surprised that it quietly solved this problem for me. All I had to do was: pytest --generate-xml --xml-report=testrail.xml And it gave me one combined XML, even with parallel runs and retries. No extra merge step, no custom code. The XML already included logs, stdout/stderr, flaky test information, screenshots etc. Uploading to my test management tool was finally a single step instead of three, supposedly made my sync with devops team much lesser as they only needed to use the test rail command to upload the xml. If you are using pytest and trying to link your tests with an test management tool, try this before going for other CI plugins https://github.com/reporterplus/pytest-html-plus Phew!  ( 6 min )

State-driven programming is a style where the current state of data drives the computation, rather than relying heavily on conditional statements (if/else) scattered throughout the code. This approach is particularly useful when tracking sequences, patterns, or logical transitions in a dataset. In this post, we’ll use a practical example: counting connected components in a linked list based on a subset of its values. You are given: head of a linked list containing unique integers. An array nums, a subset of the linked list values. Return the number of connected components in nums, where two values are connected if they appear consecutively in the linked list. Example 1: Input: head = [0,1,2,3], nums = [0,1,3] Output: 2 Explanation: [0, 1] is one component, [3] is another. Example 2: Inp…  ( 7 min )

Cloudflare, one of the world’s largest cloud security providers, faced a major dashboard/API outage on September 12, 2025 — all because of a subtle coding error. In a surprising twist, Cloudflare engineers accidentally “DDoSed” their own infrastructure. The culprit? A React dashboard update that triggered a flood of redundant API requests, overwhelming the company’s control plane. The incident unfolded quickly: At 16:32 UTC, Cloudflare released a new dashboard build containing a bug in its React frontend. By 17:50 UTC, a new Tenant Service API deployment went live. Only seven minutes later, at 17:57 UTC, the dashboard’s faulty logic caused a sudden spike in identical API calls, pushing the Tenant Service toward outage. Engineers scrambled to scale up resources and apply patches. At f…  ( 8 min )

Photo by Gabriel Heinzer on Unsplash For as long as I can remember as a developer, I’ve been told: Master the command line — it unlocks a whole new level of productivity. I always neglected that advice, thinking it was meant for people with extraordinary memory. How can a normal person memorize all the ls arguments? How do you remember the order of parameters in find? And how on earth do you get used to the quirky syntax of bash? About a year ago, I read The Pragmatic Programmer, 20th Anniversary Edition, which once again strongly urged me to master the command line. Since I otherwise liked the book, I decided to give the shell one more try. Quickly I discovered two fascinating things that completely changed my attitude toward it: You don’t have to memorize everything. Instead of fixating …  ( 9 min )

DevOps engineering is not for everyone. While there are many benefits to being a DevOps engineer, there are also many downsides. In my point of view, every benefit can become a disadvantage. It depends on what kind of person you are. In this article, I will cover the reasons why some people should not choose DevOps as a career. Here are some reasons you might regret choosing DevOps as your career. There is no industry standard for DevOps (actually, it exists, but only a few people know about it). The concept of what a DevOps engineer should do is unclear in many companies. It means that, as a DevOps engineer, your responsibilities will vary across the different companies. For example, James, who works for 404 Found Inc., is responsible only for the CI/CD pipeline automation. However, the …  ( 9 min )

Public attention to blockchain started with Bitcoin and its peers, but growing awareness has highlighted an environmental side effect: the energy used to power the network. The term “green blockchain” has emerged to describe efforts that reduce blockchain’s carbon footprint while preserving its core benefits—decentralization, security, and transparency. Why blockchain can be energy-intensive Many networks rely on a mechanism called Proof of Work (PoW). In PoW, a global race happens as computers solve complex puzzles to validate transactions and add them to the public ledger. The winners earn rewards, and the competition can push energy use to very high levels. Bitcoin is the most cited example of this pattern, where vast amounts of electricity power mining farms around the world. What “gre…  ( 7 min )

ew-responsive-store v0.0.3: The Ultimate Cross-Framework Storage Solution Introduction In the ever-evolving landscape of frontend development, managing persistent state across different frameworks has always been a challenge.

Developers, product builders, and tech leaders know: supply chains today are powered by data, not just trucks. The faster and more reliably businesses can exchange information with their partners, the more competitive they become. This is where electronic data interchange (EDI) has evolved into a mission-critical technology. Many teams spend time researching different edi software providers, only to find that the real challenge isn’t adoption—it’s making EDI systems flexible, API-driven, and developer-friendly. Why Traditional EDI Doesn’t Work Anymore On-premise systems were designed for a different era. Their drawbacks include: Complex Mapping – Every change requires manual, time-consuming updates. High Costs – Infrastructure and consulting fees weigh down budgets. Delayed Deployments – New partner onboarding can drag on for months. The Rise of Cloud-Native EDI Modern platforms bring a developer-first mindset: API-First Design – Connect EDI directly into apps, ERPs, and workflows. Rapid Deployment – Launch new integrations in days, not quarters. Scalable Infrastructure – Automatically supports growing data volumes. Transparent Pricing – Removes the complexity of hidden costs. Business and Technical ROI Beyond technical efficiency, businesses benefit with: Fewer Errors – Reduced chargebacks and compliance headaches. Cash Flow Acceleration – Faster invoicing and payments. Improved Collaboration – Stronger relationships with partners who value speed. Future-Proofing with Modern EDI The future of EDI is about real-time, API-first solutions that empower both business and development teams. Providers like Orderful are already setting the standard for how EDI should work in the modern supply chain.  ( 6 min )

He became unprofessional, violated trust, and refused to respect NDA terms or return the mobile app code that consumed our APIs. The bigger risk was not the code itself, but the fact that he still had an active client wired directly to our backend APIs. If left unchecked, he could continue consuming and potentially misusing our services indefinitely. The team needed a solution, and I was asked to take control of the situation. I decided the best way to handle this was professionally and technically, without confrontation. Instead of chasing the developer, I focused on wha…  ( 8 min )

In the digital era, a website is one of the most important assets for any business. To ensure smooth performance, security, and scalability, sometimes a company needs to migrate its hosting. Hosting migration is the process of moving a website, databases, and applications from one hosting provider to another. This process must be handled carefully to avoid downtime and data loss. There are several reasons why businesses choose to migrate hosting: Better Performance Scalability Security Cost Efficiency Support & Reliability To ensure a successful migration, here are the steps usually taken: Evaluate Needs Choose the Right Hosting Provider Backup Data Migrate Files and Databases Update DNS Settings Testing Monitoring Faster website performance Increased server capacity Improved security system Better user experience Higher customer trust Hosting migration is not just about changing service providers, but about ensuring that your website runs optimally to support business growth. With proper planning and execution, migration can be done smoothly without disrupting operations.  ( 6 min )

In the fast-evolving landscape of web development, React has emerged as the dominant player in the JavaScript ecosystem. Its robust component-based architecture and extensive community support have made it the go-to choice for developers building modern web applications. However, this dominance, while beneficial in many ways, has begun to raise concerns about slowing innovation within the space. The prevailing question is whether React's widespread adoption is inadvertently stifling the emergence of new frameworks and paradigms that could drive the next wave of innovation. In this blog post, we will explore React's strengths, examine its impact on innovation, and discuss potential alternatives and enhancements to foster a more dynamic development environment. React's rise can largely be at…  ( 8 min )

When building a website, CSS (Cascading Style Sheets) is the key to making your pages visually appealing and user-friendly. But did you know that CSS can be applied to HTML in different ways? Understanding the three main types—inline, embedded, and external CSS—is essential for writing clean, maintainable code. In this post, we’ll explore each type, their syntax, advantages, disadvantages, and when to use them. Inline CSS means writing styles directly within an HTML element using the style attribute. Example: xml This is a paragraph with inline style. Advantages: Quick and easy to apply. Perfect for testing small changes. Styles affect only the specific element. Disadvantages: Code becomes cluttered in large projects. Poor maintainability a…  ( 7 min )

ShannonBase (by Shannon Data AI) is a MySQL-compatible HTAP (Hybrid Transactional/Analytical Processing) database designed and optimized for modern big-data and AI workloads. Think of it as "MySQL for the AI era": it keeps familiar SQL and operational semantics while adding native embedding/vector support, built-in machine learning, a columnar in-memory engine, and a lightweight JavaScript runtime. The result is a unified platform where OLTP, OLAP, vector search and ML workflows can run together with minimal data movement. https://github.com/Shannon-Data/ShannonBase Key Design Principles Zero Data Movement: keep data, embeddings, models and inference as close to storage as possible - inside the database - to reduce latency, cost and operational complexity.

Welcome back! After mastering Docker deployment, networking, and orchestration, it’s essential to know how to identify, troubleshoot, and fix issues. Containers are isolated, but problems can arise anywhere — from images, networks, volumes, or Swarm services. Possible causes: Incorrect command or entrypoint Missing environment variables Port conflicts Fix: docker logs docker inspect Check logs for errors. Verify environment variables and ports. Possible causes: Network issues Wrong image name/tag Docker Hub limits Fix: docker pull nginx:latest docker login docker system prune -f Ensure network access and correct image name. Possible causes: Permission errors Wrong mount paths Fix: docker volume ls docker volume inspect Correct ownership and paths. Use chown if needed. Possible causes: Port conflicts Containers can’t communicate Overlay network misconfiguration Fix: docker network ls docker network inspect docker exec -it ping Verify networks and connectivity. Possible causes: Service not running on nodes Secrets/configs not applied Rolling updates fail Fix: docker service ls docker service ps docker stack ps docker service logs Check node status, service tasks, and logs. Use docker inspect to understand container configuration. Check logs with docker logs -f. Prune unused resources: docker system prune -f. Use docker stats to monitor real-time resource usage. Run a container with a wrong command and fix it using logs. Simulate a network conflict and resolve using docker network commands. Break a volume mount and fix permissions. Deploy a Swarm stack and troubleshoot service failures. ✅ Next Episode: Episode 26 — Docker Image Optimization & Best Practices — make your images faster, smaller, and more secure for production.  ( 9 min )

The Experiment Begins: An Alarming Cloud Bill For every team building AI Agent applications, the initial excitement of the technology is quickly tempered by a cold reality: the cloud server bill. Unlike traditional web apps, AI Agents have a highly bursty usage pattern: users may interact heavily for a few minutes, followed by hours of inactivity. Yet the servers reserved for each user session—whether EC2 instances or Docker containers—burn cost 24/7. To quantify this hidden waste, we ran a simple—but expensive—experiment. We spent $1,000 to simulate a typical AI Agent scenario under two architectures and tracked exactly where every dollar went. The results were striking, confirming a key insight: under traditional deployment models, up to 90% of backend costs are spent on “idle time.” T…  ( 8 min )

Caching adalah teknik menyimpan data sementara agar lebih cepat diakses di kemudian hari. Dengan caching, aplikasi bisa mengurangi beban server, menghemat bandwidth, dan mempercepat respons ke pengguna. Namun, setiap jenis cache punya cara kerja dan kasus penggunaan yang berbeda. Browser Cache (HTTP Caching) Cara Kerja Browser otomatis menyimpan resource (gambar, CSS, JS, bahkan response API) sesuai header HTTP yang dikirim server. Header yang umum: Cache-Control: max-age=3600 → simpan response selama 1 jam. ETag → validasi apakah resource berubah. Last-Modified → mirip ETag tapi berbasis timestamp. File statis: gambar, CSS, JS. API semi-dinamis: misalnya data profil user, daftar produk yang jarang berubah. Hati-hati pada data sensitif (misalnya API dengan token), jangan asal…  ( 7 min )

Nearly half of the work needed to convert Figma to production-ready Flutter code is still repetitive. Add in the fact that AI-generated code can be unreliable and vibe coding becomes an extra workflow rather than a solution. In my decades of software implementation experience, and after speaking directly with more than 150 Flutter developers, I’ve come to the conclusion that the real key lies not in shortcuts, but in design principles to build prototypes and then apply the hard earned skills to create value, like customize code or solve complex logic. Based on those conversations, here are the approaches that are actually working in the field today. Path 1: Automation (recommendation: HuTouch) The first approach is automation.

Kalau kita deploy aplikasi ke server/VPS, sering muncul pertanyaan: “Berapa core CPU dan RAM yang harus saya kasih ke aplikasi ini?” atau “Kalau traffic naik, saya harus scale up atau scale out?”. Jawabannya: jangan langsung tebak-tebak. Ada alur step-by-step yang bisa dipakai supaya tuning aplikasi lebih terukur, resource nggak boros, dan scaling lebih mulus. Jangan langsung kasih 8 core atau 16 GB RAM. Coba mulai dengan resource kecil misalnya 1–2 core dan 2–4 GB RAM. Kenapa? Lebih gampang lihat bottleneck. Kita tahu seberapa efisien aplikasi sebelum di-boost. Kalau dari kecil udah boros, berarti ada yang perlu dioptimasi. Sebelum mikirin scaling, pastikan aplikasi kamu pakai resource dengan benar.

Introduction: Why APIs Matter In the modern web, APIs are the glue that lets apps talk to each other. Whether you’re checking the weather on your phone or processing payments in an e‑commerce store, there’s probably an API working quietly in the background. An Application Programming Interface (API) is a set of rules that lets software applications communicate. Think of an API as a waiter in a restaurant: You (the client) tell the waiter what you want. The waiter (API) takes your order to the kitchen (server). The kitchen prepares the dish and gives it back to the waiter. The waiter delivers it to your table. No need to know the kitchen’s recipe — you just use the menu. Most modern APIs follow a request–response cycle: Client sends a request to a specific API endpoint. Server processes t…  ( 7 min )

In previous blog posts, I discussed the foundation of the useEffect hook and when not to use it. In this post, I'll explore its lifecycle. useEffect is primarily used to synchronize React components after side effects, which are operations outside of React's main rendering system. The Effect runs after the component mounts, so we should consider React's component lifecycle and useEffect's lifecycle separately. The React documentation mentions this in bold, which I'll share after this brief explanation. React components go through three stages: mount, update, and unmount. However, useEffect needs to synchronize less frequently or more frequently than the component's cycle. Here's an example from the React documentation. This component has a dropdown menu, where a user can choose a room ID: …  ( 8 min )

O que é uma API? Vivemos num mundo em que diversos sistemas, plataformas e aplicações precisam se comunicar entre si o tempo todo. Seja quando você: pede um carro por um aplicativo, faz um pagamento online, ou consulta o clima do dia, há algo funcionando por trás: as APIs — Application Programming Interfaces. Essas APIs são pontes que conectam sistemas diferentes, permitindo que troquem informações de forma segura, estruturada e eficiente. Definição Simples API (Interface de Programação de Aplicações) é um conjunto de regras, protocolos e definições que permitem que um software interaja com outro. Imagine que a API é como um garçom em um restaurante: Você (cliente) faz o pedido; O garçom (API) leva seu pedido à cozinha (servidor); A cozinha prepara e envia o prato de volta; O garçom te entrega o prato. Você não precisa saber como a cozinha funciona — apenas interage com o garçom. Essa é a ideia por trás das APIs: abstrair a complexidade interna e fornecer uma forma fácil de comunicação entre sistemas. Como funciona uma API? Requisição: O cliente (ex: seu navegador ou aplicativo) envia uma solicitação. Processamento: O servidor recebe e processa essa solicitação. Resposta: O servidor envia de volta os dados solicitados. Essa troca normalmente acontece por meio do protocolo HTTP, que usa métodos (como GET, POST) e códigos de status (como 200, 404) para indicar o que foi feito e o resultado da operação.  ( 6 min )

A deep dive into Infrastructure as Code, CI/CD automation, and cloud architecture best practices Most DevOps tutorials barely scratch the surface — a container here, a pipeline there.

Ever stared at [] + {} and thought, “Wait… what did I just do?” You’re not alone. JavaScript’s type coercion has caused more facepalms, late-night Googling, and “why is this happening?!” moments than any other feature in the language. But here’s the secret: JS isn’t broken—it’s following its own set of perfectly logical rules. Once you understand them, you’ll stop cursing your code and start actually enjoying those “wait, how did that happen?” moments. So, what is this mysterious “type coercion” in JavaScript? Simply put, it’s JavaScript automatically converting one type into another—like turning a number into a string when you do "Age: " + 25, or a boolean into a number when doing true + 1. It exists because JS was designed to be flexible and forgiving, especially in browsers where script…  ( 11 min )

For years, we senior engineers have been the cartographers of application state. We’ve drawn intricate maps with the precise, unyielding lines of Redux. We knew the rituals by heart: the defining of actions, the crafting of reducers, the composing of selectors, the weaving of middleware. It was a grand, formal architecture. It brought order to chaos. It was predictable, testable, and for a time, it was perfect. But as our applications grew from simple pages into rich, interactive experiences, the ceremony began to feel… heavy. We found ourselves writing more boilerplate than business logic. We were mapping the territory so meticulously that we had less time to explore it. The modern era isn't about tearing down the old cathedral. It's about discovering new, nimble tools that allow us to sc…  ( 10 min )

For the senior developer, building a modern web application has often felt like conducting a complex orchestra. Every section—the strings of the UI, the percussion of state management, the woodwinds of API calls—must play in perfect harmony. But we've always faced a fundamental tension: the server, powerful and close to the data, versus the client, dynamic and close to the user. We've built intricate systems to manage this duality: server-side rendering (SSR), static site generation (SSG), and client-side fetching. We’ve made it work, but the mental load was high. The lines were blurred. Next.js 15, with its matured implementation of React Server Components (RSCs), doesn't just add a new feature. It provides a new philosophy. A new mental model.

Picture this: It’s 2 AM, you’re deploying a “simple” column type change to production, and suddenly your entire application is down because the table lock is taking forever. Your phone starts buzzing with angry Slack notifications, and you’re frantically trying to explain to your team why the “5-minute migration” has been running for 30 minutes. The shadow table strategy is like having a stunt double for your database table. Instead of modifying your original table directly (and potentially bringing your application to its knees), you create a shadow clone new table with the desired structure, gradually copy data over, and then perform a lightning-fast switcheroo. Here’s the basic flow: Traditional ALTER TABLE operations can be absolute nightmares in production if you’re dealing with webs…  ( 12 min )

Day 5 – for loop In case you’d like to revisit or catch up on what we covered on Day Four, here’s the link: https://dev.to/babsarena/learn-bash-scripting-with-me-day-4-fo7 In Bash, a for loop is used to iterate over a list of items (strings, numbers, files, command outputs, etc.) and execute a block of code repeatedly for each item. It helps automate repetitive tasks without having to write the same command multiple times. Iterate simply means to repeat a process step by step. Imagine you have a basket of fruits: If you iterate over the basket, you: Pick up the apple → do something with it. Pick up the banana → do something with it. Pick up the cherry → do something with it. First, we’ll create a file that contains a list of fruits. Later, we’ll use this file in a for loop. The imag…  ( 7 min )

For years, we senior engineers have been the architects of the React ecosystem. We’ve laid the bricks of class components, orchestrated the symphony of hooks, and meticulously welded together data flows with Redux or Context. We’ve built magnificent, performant applications, but if we're honest, we've also written our fair share of boilerplate. We’ve created custom hooks to do what the framework perhaps should have. We’ve patched over the seams between the React world and the outside world. React 19 isn't a revolution; it's a renaissance. It’s the framework maturing, looking at the art we’ve created with its tools, and thoughtfully handing us a new set of refined brushes and richer pigments. It’s about removing friction, embracing the patterns we’ve collectively established, and baking the…  ( 10 min )

If you thought the AI race was just Silicon Valley’s game, think again. ASML, that Dutch semiconductor giant you might know for making the complex machinery behind your favorite chips, just dropped a cool $1.5 billion on a European startup named Mistral AI — and no, this isn’t just another Boeing 747-sized investment with a coffee break in between. They’re aiming to build an "OpenAI killer" right in Europe's backyard. Let’s be real: ASML isn’t exactly your neighborhood software startup. They build the machines that make semiconductors, which are the brains of every device you love and occasionally hate for crashing on you. But here’s the kicker — the AI boom needs silicon crafted with mind-boggling precision. ASML’s gotta keep the pipeline flowing upstream and downstream. Placing a $1.5 bi…  ( 7 min )

Letzte Woche hat mich ein Kunde gefragt: "Warum bekomme ich kaum noch Traffic, obwohl meine SEO eigentlich gut ist?" Die Antwort war ernüchternd: Seine Zielgruppe googelt nicht mehr – sie fragt ChatGPT. Während wir Entwickler noch fleißig unsere Meta-Tags optimieren und Keywords analysieren, hat sich das Spiel bereits geändert. KI-Systeme wie ChatGPT, Claude und Co. werden zur ersten Anlaufstelle für Informationssuche. Und rate mal, wessen Inhalte dort auftauchen? Richtig – nicht die, die nur für Google optimiert sind. Das ist kein Zukunftsszenario – das passiert jetzt gerade. Und wenn du nicht aufpasst, wird deine Expertise komplett unsichtbar, egal wie gut deine technischen Skills sind.

Most ML models die in notebooks. I built one that retrains itself, scales to hundreds of users, and deploys in minutes — here’s the exact AWS + Docker + CI/CD stack I used. In this project, to keep the costs as low as possible, the Machine Learning model was trained on the local machine then uploaded the artifacts to the AWS platform. This project also demonstrates an entry-level MLOps workflow — retraining and redeployment are automated through CI/CD, but advanced MLOps features like data versioning, model registry, and monitoring are not yet implemented. There are a few prerequisites for this project and they are the following: Docker Python CI/CD pipelines basic usage of GitHub basic knowledge of AWS services Link to the code is here — let’s get started!

Problem I needed to install and switch between older Node.js versions (like 10.12.0 and 12.19.0) on Windows. I first tried using nvm-windows, but every time I installed an old version, it failed with errors like: error installing 10.12.0: The system cannot find the file specified. The issue was that nvm-windows tries to download matching npm zip files, and those archives no longer exist for many old Node releases. This meant I couldn’t get the versions I needed without messy manual fixes. Instead of fighting with nvm-windows, I switched to Volta, a modern JavaScript toolchain manager that works perfectly on Windows. Here’s the complete process I followed: Using winget (recommended): winget install Volta.Volta Or download the latest .msi installer from Volta releases. After installation, restart your terminal so Volta is added to your PATH. volta --version Now I could install older Node.js versions without errors: volta install node@10.12.0 volta install node@12.19.0 Check versions: node -v npm -v For projects that depend on specific Node versions, Volta can “pin” the version: cd my-legacy-project volta pin node@10.12.0 This adds the Node version to the project’s package.json. Now whenever I enter this folder, Volta automatically switches to Node 10.12.0. Another project can have Node 12.19.0 pinned the same way, without conflicts. ✅ Final takeaway: nvm-windows. Volta, installation is simple, switching is automatic, and everything just works.  ( 6 min )

Introduction In the previous article, we explored how to create a form based entirely on signals. However, that was a simple form with no business logic and, most importantly, no validation. This article aims to detail how we can write our business logic simply and in a scalable way.

After learning about permissions, ownership, and package managers in Part 3, I realized that being comfortable with Linux also means being able to manage files, automate tasks, secure access, and work across systems. This part of my journey dives into some of the most practical everyday tools of a DevOps engineer: archiving, cronjobs, SSH, SCP, virtual machines, and key pairs. One of my first real struggles was handling log backups. I had thousands of log files in /var/log/, and transferring them individually was a nightmare. So I used tar: tar -cvf logs.tar /var/log/ Output: /var/log/syslog /var/log/auth.log /var/log/kern.log ...

What I Learned from Studying SEO: Notes, Checklist, and Developer Takeaways I recently spent time studying Search Engine Optimization (SEO) — not because I wanted to be a marketer, but because I wanted to understand how information should be structured, presented, and optimized. For me, SEO is not just about “ranking higher.” It’s about clarity, trust, and structure — skills that are directly relevant to being a developer. This post is a record of what I learned, the checklist I built, and how I believe this experience connects to my growth as a developer. When I build projects or write technical blogs, I don’t just want them to exist — I want them to be accessible and professional. Without clear metadata or a sitemap, even a great project can feel incomplete. Without optimized pe…  ( 8 min )

AI has the potential to transform industries, but many AI projects struggle to meet their goals. These projects often fail to scale or deliver expected results. While the technology itself may be strong, the reasons behind failure typically extend beyond the technology. In many cases, AI projects falter because they don't align with market needs or fail to deliver long-term value. The Case of Artifact Artifact, developed by Instagram’s co-founders, is a clear example of how even high-profile AI projects can struggle. Positioned as the "TikTok for news," the app initially attracted significant attention and saw a solid number of downloads. However, it failed to retain users. The issue wasn’t the technology itself but that the app’s AI-driven news curation didn’t integrate into people’…  ( 8 min )

Testing comprehensive Node.js applications with complex layered architectures presents a unique challenge: maintaining consistent patterns and architectural boundaries across hundreds of test files while ensuring each layer is tested appropriately. After architecting and implementing test suites across multiple production systems, generating over 200 test files with rigorous patterns, I've developed an approach that transforms testing from an ad-hoc craft into a systematic engineering discipline: AI-powered test generation through custom Claude commands that encode architectural testing knowledge. This isn't about replacing human expertise with AI generation. It's about codifying years of testing architecture decisions into reusable, consistent patterns that scale beyond individual develop…  ( 16 min )

The world is moving faster than ever, and our digital lives are stored everywhere in Google Drive, Dropbox, iCloud and dozens of other services. But here’s the problem: our files are not truly ours. Most mainstream cloud storage solutions come with hidden costs: For those of us who want to own our data and trust no one but ourselves, these options just don’t cut it. DriveLite is built for people, not corporations. Think of it as Google Drive for people who love privacy. I started DriveLite because I believe in: Digital Freedom -> Everyone deserves to own their files without being tracked. Trustless Security -> Privacy should come by default, not as an afterthought. Community Power -> People around the world are tired of surveillance capitalism open-source gives us a way out. I don’t want to rent my digital life to big tech anymore. I want a solution I can trust, run myself, and share with others.

When people first start using Docker, the two terms that come up again and again are Dockerfile and docker-compose.yml. They sound similar, both are configuration files, and both are written in plain text. But they are not the same thing and they serve very different purposes. A Dockerfile is a recipe. Imagine you want to bake a cake. The recipe tells you what ingredients to use, what order to mix them in, and how long to bake. Similarly, a Dockerfile tells Docker how to build an image. For example, you might say: Start with Python version 3.11 as the base Copy my application files into the image Install the required dependencies Tell the container to run python app.py when it starts The end result is an image. That image is like your finished cake. You can share it, store it, or run it an…  ( 7 min )

The Reality Bridge Day: From Quantum Potential to Classical Certainty Day 12 of my QuCode quantum computing challenge explored one of the most profound and practical aspects of quantum mechanics: quantum measurement and the no-cloning theorem. Today's focus on projective measurement and wavefunction collapse revealed how quantum information transforms into the classical information we can observe and use. The QuCode insight that "every observation shapes reality — in quantum mechanics and in life" perfectly captures today's learning. Quantum measurement isn't just about extracting information from quantum systems; it's about the fundamental process by which quantum possibilities become classical realities. The no-cloning theorem shows us that quantum information is fundamentally differen…  ( 17 min )

The story of how I went from spaghetti code to a maintainable, scalable backend architecture I used to be that developer. You know the one – writing everything in the controller, mixing business logic with data access, and creating dependencies so tangled that changing one line of code felt like defusing a bomb.

It's no secret that it's hard right now for juniors to find a job in tech. The market has shifted dramatically, and entry-level positions are becoming increasingly rare. Companies are looking for senior developers who can hit the ground running, and the traditional junior developer role seems to be disappearing. The rise of AI has fundamentally changed the equation. Tasks that used to be perfect for junior developers - writing boilerplate code, fixing simple bugs, implementing basic features - can now be handled by AI assistants. Why would a company hire a junior developer when a senior developer with AI tools can be 10x more productive? This creates a vicious cycle: juniors can't get experience because there are no junior positions, and there are no junior positions because companies wa…  ( 7 min )

Intro GitHub quietly turned the humble Issue into a launch button.

If you’ve ever joined a new project, switched machines, or tried out a new language, you probably know the drill: hours spent configuring your environment before you even write a single line of code. Ironically, developers often spend more time setting up environments than actually building features. Let’s dig into why that happens, and how you can avoid the trap. Environment setup sounds simple on paper: install a language, add dependencies, configure a database, and you’re good to go. But in reality: Version conflicts: Your project needs Node.js 18, but your global install is on 20. Dependency hell: One library update silently breaks everything. OS differences: Works fine on Linux, but fails on macOS or Windows. Documentation gaps: Instructions are outdated, or worse—missing. …  ( 7 min )

This was a topic I wanted to get to for a while. There's 2 common ways (but other less common ways) to do shadows for 3D graphics. Raytracing is the most accurate and simple but very expensive. When we can't afford that, the stock standard approach is shadow mapping because it's inexpensive and works well enough. This is what most games you've seen use and you can usually tell by the characteristic artifacts where shadows look "pixelated" and that's what I want to implement. There are tons of tweaks to shadow maps to improve results but for now I'm just looking at the simpler version. The intuition here is that we treat each light like a camera and then we take a picture of the scene with it. This picture is just a depth map. Then when we render the scene for each point we compare t…  ( 21 min )

Introduction In DevOps, checking out code from a repository is often treated as a trivial step. While mandatory, this is just the starting point. Real production deployment involves a series of critical logical steps—validating data structures, resolving dependencies, optimizing builds, and configuring environments. Skipping these steps may seem convenient but can lead to performance bottlenecks, higher operational costs, and even environmental impact. The Gap Between Checkout and Deployment Code Checkout: Cloning or fetching files from a repository (Git, SVN, etc.) Brings the code, but does not optimize it. Deployment: Moving the code into production with intelligent validation and optimization Data structure validation: Ensures schema and data integrity. Dependency resolution: Confirms c…  ( 6 min )

The Problem: Coordination is the New Bottleneck In the age of AI, we have access to an infinite workforce of intelligent agents. But they operate in chaos—without a common language, without trusted infrastructure, without accountability. The bottleneck isn't execution anymore; it's *coordination.

How I Built a Security Guardian for Kiro I was coding late one night when it hit me: I had no idea if my AI-generated code was secure. Like most developers, I was trading speed for security without even realizing it. Then I saw this testimonial on kiro.dev: "In just four lines into a spec, Kiro was able to write user stories like a product manager..." That's when KiroSpecGuard was born. I created a security spec with just four natural language lines: "Prevent basic XSS vulnerabilities in all user input handling" "Ensure all user input is sanitized before rendering to HTML" "Block direct DOM manipulation with untrusted data" "Follow OWASP Top 10 security practices" Kiro converted these into working security logic that scans my code as I type. No complex setup. No security expertise needed. The most impressive moment? When Kiro caught an XSS vulnerability in my code before I even saved the file. My on_file_save.kiro hook automatically flagged dangerous patterns like .innerHTML = with user input and suggested the secure alternative. Instead of spending hours writing security rules, I got instant protection. Instead of dreading audits, I had documentation automatically generated. Security shouldn't be an afterthought. With KiroSpecGuard, it's built right into my workflow - like a seatbelt that puts itself on while I drive. In just one weekend, I built something that would have taken me weeks. All because Kiro lets me describe what I need in plain English, then handles the heavy lifting. kiro #hookedonkiro  ( 6 min )

Introduction Software development is undergoing another seismic transformation. Artificial intelligence is no longer merely an add-on or a supplementary tool—it is a first-class participant at every stage of the software lifecycle. This evolution has led to the emergence of agentic development environments, where AI systems act as collaborators, not just code generators. At the forefront of this new paradigm is Kiro AI IDE, an agentic, spec-driven environment that aims to bridge the chasm from ideation (“vibe coding”) to robust, production-grade systems. This guide provides a comprehensive, hands-on exploration of how to use Kiro to build, launch, and maintain a Python-based AI application, following the entire process from signup to deployment.

Most would panic. However, Donnie Prakoso, Principal Developer Advocate at AWS, turned to Amazon Q CLI. His methodical approach - requirements, task-based workflows, MCP tools - saved the day. But his key insight changed everything: "It's not about the AI tool itself, but how you integrate it into your workflow." This real life scenario inspired me with the idea to build a full self-service serverless AI app, a Retrieval Augmentation Generator (RAG) - based Presentation Generator by using Kiro and leveraging these key capabilities: Serverless AWS architecture with Bedrock Models Real-time document pr…  ( 10 min )

Hi there! Here you'll quickly learn how to debug any website navigation from you mobile device (Android only). With USB debugging + Chrome's Dev Tools you can see any logs, network requests, etc. Android device USB data cable A trustable desktop/laptop with Google Chrome On your android you need to enable the developer mode. Usually this can be achieved by navigating to Settings => About Phone (or similar) and tapping the build number a couple of times (until it tells you the developer mode is enabled) Once you have the developer mode enabled, you need to enable the USB Debugging: Settings => Developer Options => USB Debugging (or similar) This step is just to connect your mobile device to your desktop/laptop via USB data cable. Your android system can require you to accept the USB debugging. Open the desired webpage on your mobile device (via chrome); On your desktop/laptop open the following url through your chrome browser: chrome://inspect/#devices; Within the devices tab you'll see the opened tabs from your mobile device. Select the desired and click on inspect Then a new tab will be opened, and there you can use the Chrome Dev Tools functionalities like see the logs, network requests, and even navigate the website from your desktop/laptop Official doc and more information: https://developer.android.com/studio/debug/dev-options  ( 6 min )

Apple’s new Liquid Glass design and Google’s Material 3 Expressive update promise to make our phones look fancier – but many designers and users are already grumbling. These see-through, glassy effects and over-the-top animations sound exciting on paper, but can they hamper usability in the real world? After combing through tech blogs, reviews, and dev communities, here are the key problems critics have found (with a humorous twist): Apple bills Liquid Glass as a “translucent material that reflects and refracts its surroundings” (Apple WWDC session). In other words, buttons and panels look as if they’re carved from actual frosted glass (think of iOS floating above a pretty wallpaper everywhere). The idea is to give the UI “a new level of vitality” across controls and icons. Apple’s Liqui…  ( 8 min )

When you start working with JavaScript or TypeScript, you’ll notice two different styles of importing libraries: // Style 1 import * as moment from "moment"; // Style 2 import moment from "moment"; At first glance, these two look similar. But depending on the project, one may work while the other gives you an error. So why do some packages “require” import * as? And when can you use the cleaner import … style? module systems and TypeScript compiler settings. There are two main ways JavaScript code is packaged: The original Node.js system. Uses require and module.exports. // moment/index.js module.exports = moment; // Using require const moment = require("moment"); The modern JavaScript standard. Uses import and export. // modern-style module export default PDFDocument; // Using import…  ( 7 min )

When I signed up for the Kiro Hackathon, I wasn’t sure if I’d be able to honor my registration. Life had thrown me into a period of burnout and low energy, and the idea of diving into code from scratch felt overwhelming. Still, I didn’t want to give up. I wanted to create something simple yet meaningful — an AI-inspired companion that could resonate with neurodivergent users like myself. That’s when I discovered how much Kiro could simplify the process. Starting with Spec Instead of Stress! Within seconds, Kiro’s agent transformed my description into a structured codebase. I wasn’t staring at chaos — I was staring at a working app skeleton. It was like someone had cleared the fog and handed me a path forward. For someone navigating burnout, this was a game-changer. I could skip the heavy l…  ( 7 min )

We need to talk about technical debt. Not the scrubbed, executive-friendly version that gets discussed in board meetings, but the brutal reality that's probably making your workday miserable right now. The Technical Debt Reality Check IDC just released research showing that technical debt has become one of the most critical business drivers for 2026. But here's what they won't tell you in the executive summary: this isn't just a business problem—it's a developer quality-of-life problem. We're dealing with: Legacy Spring applications running on ancient versions with security vulnerabilities Patchwork architectures where every change feels like defusing a bomb Data quality issues that make AI initiatives laughably impossible Integration nightmareswhere adding a simple API endpoint becomes a …  ( 10 min )

The Spark: Why Stories Need Better Protection It started with a conversation. I was talking to a friend who's a talented writer from Nigeria, and she told me about how she'd been writing stories online for years but had no way to protect her work or get fairly compensated when her stories went viral. She'd seen her work shared across platforms without attribution, and when a small production company reached out about adapting one of her stories, she had no legal framework to negotiate a fair deal. That's when it hit me: we need a platform where stories become intellectual property, not just content. The more I researched, the more I realized this wasn't just her problem. Writers across Africa, MENA, and the Global South were creating incredible content but lacked the infrastructure to pr…  ( 15 min )

A deep dive into why that innocent import statement is costing you more than you think Picture this : You're debugging a production issue at 2 AM. Your Python application is taking 30 seconds to start up in production, but only 5 seconds on your local machine. After hours of investigation, you discover the culprit isn't complex business logic or database connections—it's dozens of unused imports accumulated over months of development, each one silently executing initialization code and consuming memory. This isn't a hypothetical scenario. It's the reality for countless Python applications running in production today. Every unused import in your codebase is a small performance tax that compounds over time, creating measurable impact on startup time, memory footprint, and overall application…  ( 12 min )

When building an API, you often need to handle complex query parameters. If you're just coding casually, this might not be a concern, but when building a real-world solution, pagination, filtering, and sorting are essential for creating a robust and scalable API. In my current project with NestJs, I faced this challenge. Initially, I thought, "Easy, I just need to write the DTOs"—but it wasn't that simple. Today, I'm going to show you how to implement complex filtering in a NestJs endpoint. First, we need to create a new Nest project. If you've already installed the CLI, this is a simple step. If not, I highly recommend installing it. nest new complex-query-filters Since we'll need to validate and transform our DTOs, let's install class-validator and class-transformer packages. npm i cla…  ( 9 min )

So, you want to keep your data safe and steer clear of expensive mistakes? Understanding ISO 27001 is honestly a pretty smart move. ISO 27001 is an international standard that helps you protect your sensitive information from cyber threats and internal slip-ups. It lays out clear rules for managing security risks, which helps you build trust with customers and partners. You might think ISO 27001 is just for the big guys, but nope—it works for any organization, no matter your size or industry. Meeting this standard can open up new business opportunities. It also makes it easier to follow other security rules later on. By following ISO 27001, you lower your chances of data breaches and avoid those annoying penalties that come from sloppy security.

In the DevOps world, speed is everything. CI/CD pipelines let us push changes to production multiple times a day. Containers and cloud make scaling effortless. But in this rush for speed, one critical question often gets ignored: Are we deploying securely? That’s where cybersecurity comes into play. Traditionally treated as a separate discipline, cybersecurity is now bleeding into DevOps responsibilities — giving rise to DevSecOps. If you’re a DevOps engineer, understanding where you fit into this picture is essential.

I recently built CADemy, a web-based 3D modeling education platform, and my favorite thing about Kiro is how it completely changed the way I approached development. 💡 How Kiro Helped Me Build CADemy Vibe Coding: I broke my idea into smaller steps and worked with Kiro iteratively. The most impressive moment was when Kiro generated a full interactive 3D object manipulation setup using Three.js – saving me hours of manual coding and debugging. Agent Hooks: Automated repetitive tasks like setting up project structure, generating boilerplate code, and formatting files. This let me focus more on core features and less on routine work. Spec-to-Code: I structured clear specs with goals, inputs, and outputs. Kiro turned them into production-ready code, reducing errors and speeding up my workflow. ✨ Why I’m #hookedonkiro 📢 Tagging @kirodotdev – you made CADemy possible! hookedonkiro #WebDevelopment #AI #Hackathon #ThreeJS  ( 6 min )

Previously I have been using sanitize CSS reset. In practice it turned out to be quite extra and still needed tweaking. For now my approach is: the simpler = the better. The CSS reset from Josh Comeau is quite simple and modern: as you may see, it uses newer properties for text-wrap and interpolate-size. In the linked article you will find explanations for all the properties used. /* Josh's Custom CSS Reset https://www.joshwcomeau.com/css/custom-css-reset/ */ *, *::before, *::after { box-sizing: border-box; } * { margin: 0; } @media (prefers-reduced-motion: no-preference) { html { interpolate-size: allow-keywords; } } body { line-height: 1.5; -webkit-font-smoothing: antialiased; } img, picture, video, canvas, svg { display: block; max-width: 100%; } input, button, textarea, select { font: inherit; } p, h1, h2, h3, h4, h5, h6 { overflow-wrap: break-word; } p { text-wrap: pretty; } h1, h2, h3, h4, h5, h6 { text-wrap: balance; } #root, #__next { isolation: isolate; }  ( 6 min )

Building Event-Driven Multi-Agent Systems (or: How I Built 4 Apps Instead of 1 for a Hackathon) So here's the thing - everyone builds one app for hackathons, right? I built four. Not because I'm trying to show off but because... well, actually maybe a little bit of showing off, but mostly because exploring Kiro meant building multiple things and I wanted to really push what's possible with event-driven architectures. You can't vibe code this kind of magic. Look, I've been in the trenches. Seen teams of 10+ engineers with 10+ million in funding build these monolithic agent systems that basically... don't work. They couple everything together, agents stepping on each other's toes, no clear orchestration pattern. It's a mess. And then they wonder why their funded startup dies without findin…  ( 9 min )

When building React applications, we often focus on the happy path - making sure everything works when users interact with our app as expected. But what happens when something goes wrong? A single unhandled error can crash your entire React application, leaving users staring at a blank screen. This is where Error Boundaries come to the rescue. Error Boundaries are React components that catch JavaScript errors anywhere in their child component tree, log those errors, and display a fallback UI instead of the component tree that crashed. Think of them as a try...catch block for React components. Error Boundaries catch errors during: Rendering In lifecycle methods In constructors of the whole tree below them It's important to understand the limitations: Event handlers (use regular try...catch …  ( 10 min )

GitHub Copilot - code review assistant Pull Requests (PR) are a central part of many teams’ workflows. PRs allow us to consolidate changes into a single, manageable unit that can be communicated, discussed, and refined. But this process can be time-consuming. Because of this, I’ve been exploring GitHub copilot code review as a complement to the traditional code review process to reduce this overhead. GitHub Copilot offloads basic reviews to a copilot agent that catches issues like logic bugs, potential performance problems, anti-patterns, and even suggests fixes to improve code quality. When I first started using copilot, I primarily used it in my code editor for autocomplete and code suggestions. As copilot has grown and added new features, I have also expanded my use cases beyond my code…  ( 8 min )

Overview, Historical Timeline, Problems & Solutions You may want to store more than one value in a single variable. You do not want the values to change. In Python, you can use a tuple. A Python tuple is a fixed group of values. It keeps values in order. Once made, it cannot be changed. This is called immutable. Each item in a tuple can be any Python object. A tuple may hold numbers, strings, lists, or other tuples. Python lets you group fixed values using tuples. point = (3, 4) print(point) print(point[0]) This prints: (3, 4) 3 To write a tuple in Python, place items inside round brackets. Separate items with commas. For example, (1, 2, 3) is a tuple of three items. A tuple with no items is written (). A tuple with one item must use a comma, like (7,). Without the comma, Python will no…  ( 10 min )

I was very excited to hear about Anthropic’s announcement in May, that we now have the ability to add integrations to Claude. Connecting to remote MCP (Model Context Protocol) servers and not just local ones is a major step forward. AI systems like Claude are no longer limited by the age of their training data. They can pull in up-to-date context and use tools provided by these integrations (MCP servers). Adding MCP servers to Claude desktop is relatively straightforward, so I jumped right in. I already have a remote MCP server running and a few examples from other companies I wanted to try.

Three months ago, I was that developer who could build a decent React frontend but turned into a deer in headlights the moment someone mentioned "database schema" or "API endpoints." You know the type - great at making things look pretty, terrible at making them actually work. Then I got tired of being the "frontend person" in every conversation and decided to do something completely unreasonable: build a new backend project every single day for a month. Spoiler alert: It was one of the best terrible ideas I've ever had. Here's the thing about backend development - it's intimidating as hell when you're coming from frontend land. Frontend feels immediate and visual. You change a color, boom, you see it. You add a button, click it, it does something. Backend? You're dealing with invisible st…  ( 8 min )

From $8 star packs to $5,000 achievement-loaded profiles, here’s how clout is being sold on GitHub.” GitHub isn’t just where developers push code and fight over tabs vs spaces. It’s also where the weirdest underground market you’ve never heard of is thriving. Think less “open source utopia” and more “dark alley bazaar,” except instead of knockoff sneakers, you’re buying repo stars, followers, and even entire pre-leveled accounts. And here’s the part that makes me wince: I’ve fallen for it. Once upon a sprint, I cloned a repo with thousands of stars thinking I’d found my next dependency gem… only to discover half-baked code that didn’t even compile. My terminal looked like it had been hit with a denial-of-service attack. That’s when it clicked: stars aren’t just code kudos they’re clout. A…  ( 12 min )

For the past months, I’ve been working on something I’m really excited about: Ambitus Purus – a mobile app designed to encourage and reward rubbish disposal through community-driven challenges. The idea is simple: people upload before-and-after photos when cleaning up rubbish in their local environment. Each action earns them points, and top contributors in each area receive monthly recognition and rewards. It’s a mix of gamification + real-world impact. ♻️ The app is about 85% complete. It already has: A functioning backend with authentication (email/password login) A nearly complete admin panel The core photo-upload and points system Still on the list: a few polish tasks, user experience improvements, and final reward mechanisms. I’m sharing this here on dev.to to bring awareness to the project and hopefully spark interest. Whether you care about clean technology, gamification, or community-driven solutions, Ambitus Purus is built to create real environmental impact. I’ll be sharing more updates soon. For now, just wanted to introduce it to the community and see what you think. 👉 If this resonates with you, leave a comment or follow along — your feedback means a lot.  ( 6 min )

Python Selenium gives you multiple ways to capture the entire page, specific HTML elements, or even raw screenshot data. Let's start! The simplest approach is capturing what’s currently visible in the browser window. from selenium import webdriver driver = webdriver.Chrome() driver.get("https://www.selenium.dev") driver.save_screenshot("viewport.png") # user-friendly alias # or driver.get_screenshot_as_file("viewport_file.png") # same thing driver.quit() It captures only the visible viewport, not the full scrollable page. Take into consideration that save_screenshot() is just a wrapper around get_screenshot_as_file(). Both return True on success, False on I/O errors. Capturing the entire page depends on the browser. from selenium import webdriver driver = webdriver.Firefox() driver…  ( 7 min )

We came to the Kiro hackathon with an idea: a decentralized MMORPG — and we left the hackathon with a working prototype of Elem Game, built from scratch. We were inspired by the idea of rethinking how an MMORPG could work in a decentralized architecture. We're looking for a way to build a game world with no central server, and without requiring users to manage wallets or understand transaction mechanics — the typical barriers in Web3 that hinder player adoption. Our goal is to create a true Web3 game where: the rules are fixed and formalized, and changes happen through predefined consensus; participation is permissionless but governed by rules that apply to everyone equally; security and resilience come from architecture, not moderation; users get a smooth, familiar MMORPG experience — wit…  ( 7 min )

As a developer, you’re always looking for projects that are both technically interesting and have real-world demand. If you haven’t considered the pet industry in the USA and Canada, now is a perfect time. Millions of households own pets, and there’s a growing demand for online platforms where people can buy, sell, adopt, or list pets and related services. The USA and Canada have some of the highest pet ownership rates in the world. Pet owners spend billions annually on pets — not just buying them, but also on accessories, services, and healthcare. Yet, much of the market is fragmented: people rely on small classified sites, Facebook groups, or Craigslist to find pets. • You tap into a ready and willing user base Developing a full-featured marketplace from scratch is time-consuming and costly. This is where a Pet Listing Script becomes a game-changer: Using a ready-made script doesn’t take away your creativity — it actually lets you focus on building unique features instead of reinventing core functionality. As a developer, you get to: • Save weeks or months of development time • Ensure your platform is secure and scalable from the start • Customize the front-end and back-end to create a unique user experience • Quickly test new ideas or features without affecting the core platform In short, a Pet Listing Platform in North America is not only technically challenging and fun to build, but it also has real business potential. By leveraging a pet listing script, you can launch faster, focus on innovation, and tap into a market that’s ready and eager for digital solutions. 💡 Pro Tip: Start with a script to handle the basics, then add custom features, like AI-based pet recommendations, subscription-based breeder networks, or integrated pet services — making your platform stand out in a competitive market.  ( 7 min )

Spike Timing: The Brain's Secret to Lightning-Fast Pathfinding Imagine a swarm of robots navigating a warehouse, or autonomous vehicles plotting the most efficient route in real-time. Standard algorithms are often too slow and power-hungry for these applications, especially on resource-constrained devices. But what if we could harness the power of the brain to solve these complex problems with unmatched speed and energy efficiency? Here's the revolutionary idea: encode network paths into precisely timed spikes in a neural network. Neurons communicating with each other send signals, and the timing of these signals carries the critical information. The network learns to prioritize earlier arrivals – think of it like a rumor mill, where the first to hear the news gets the advantage. This cr…  ( 7 min )

At every wedding, birthday, or corporate gathering, guests are taking pictures. The problem is that those photos end up scattered across devices and apps, making it hard for organizers to collect and share them. That’s the problem we set out to solve with Fotify. The Idea Fotify is a real-time photo-sharing and RSVP platform that makes events more interactive: Guests scan a QR code to upload photos instantly. Hosts can display live galleries on screens during the event. Digital invitations, RSVPs, and even multi-day itineraries are managed in the same platform. No app downloads. No accounts for guests. Just instant memories, accessible to everyone. The Tech Stack Here’s how we’re building Fotify under the hood: Frontend: Next.js Backend: NestJS Database: PostgreSQL, self-hosted for full control and performance. Authentication: Google OAuth, already integrated with Passport.js. Storage & Media: Planning Cloudflare R2 (for raw photos) and Cloudflare Images (for transformations & delivery). Analytics: Umami AI Layer: Intelligent moderation & filtering to keep galleries clean and safe. This setup gives us full control, performance, and scalability, without locking ourselves into expensive managed services. Lessons Learned Hetzner is underrated. With good setup (Docker + Traefik + backups), it’s cheap, fast, and reliable. Next.js + NestJS is a perfect combo. The separation of concerns keeps development clean and scaling easier. Postgres beats MySQL for flexibility. Especially with JSON fields for handling dynamic event data. Start with authentication early. Google OAuth via Passport.js made onboarding smoother for organizers.

First of all, you need to understand who and for what tasks you are looking for. For example, if you need a developer who can adjust and adapt to tasks, then you should ask about what techniques/methods they use to learn something new, how often they are interested in new things themselves – you can ask how they would conduct research, and if they have had similar experience. If you "urgently need a developer" for "this task for a week" you must definitely consider that they will need to get familiar with the codebase and the project itself (adaptation time) – and it’s good if this takes a week or two. Ask a developer does he have such experience, and how comfortable he would work in such case (because any urgent cases usually are the most stressful ones).

I started seriously learning Python in 2020 while working on a release note generator for a co-op bank. It was easy to understand, enjoyable to work with, and a perfect excuse to learn something new. If you’re anything like me, you love experimenting, trying new things, and continuously improving. From that moment, Python became my default language for almost everything. I built REST APIs with FastAPI and Flask, analyzed data with Jupyter, created CLI apps with Click—you name it. I practically ate Python for breakfast. Funnily enough, at the time I was using TypeScript and Node.js exclusively. It wasn’t perfect for my DevOps work, but it got the job done. Then one day, I decided to fully dive into Python. I didn’t know much about it at first, but I started learning while building the relea…  ( 10 min )

Today I learned about Normalization in databases. Normalization is the process of organizing data in a database to eliminate redundancy and improve data integrity. It helps ensure that data is consistent, accurate, and easy to maintain. Reduces data duplication Ensures consistency across tables Saves storage space Makes queries more efficient Without normalization: OrderID | CustomerName | CustomerPhone | Product 1 | Ramya | 9876543210 | Laptop 2 | Ramya | 9876543210 | Keyboard Here, customer details repeat for every order. With normalization (using separate tables): Customers Table CustomerID | Name | Phone 1 | Ramya | 9876543210 Orders Table OrderID | CustomerID | Product 1 | 1 | Laptop 2 | 1 | Keyboard 1NF – Remove repeating groups, keep atomic values. 2NF – Remove partial dependency (depends on part of a composite key). 3NF – Remove transitive dependency (non-key depends on non-key). Normalization makes databases clean, consistent, and scalable – a must-have skill for any Data Analyst.  ( 6 min )

Logic's Hidden States: Unlock Debugging Superpowers with Algebraic Thinking Ever chased a bug that vanished when you added a print statement? Felt like your code was lying about its internal state? You're not alone. What if you could systematically dissect the logic driving your program, turning complex boolean expressions into manageable, visualizable forms? Imagine each possible configuration of your program – its 'state' – as a coordinate in a multi-dimensional space. 'State Algebra' provides tools to navigate and manipulate this space. Instead of just evaluating 'true' or 'false', we represent and transform sets of states using algebraic operations. This allows for a more granular view, breaking down complex logic into fundamental building blocks. Think of it like simplifying a comp…  ( 7 min )

Why predictive systems make decisions without subjects, and how accountability injection can restore responsibility in law, finance, education, and healthcare. *Introduction When you are denied a university admission letter, refused a credit increase, or flagged by a medical audit, the decision increasingly comes from a system rather than a person. It is not a professor who rejected your application, not a banker who cut your limit, not a doctor who reviewed your scan.

Unlike class-based languages, JavaScript uses prototype-based inheritance, allowing objects to inherit properties and methods from other objects. In JavaScript, every object has an internal [[Prototype]] property that references its parent object. When accessing a property on an object, if it doesn't exist, the prototype chain is searched for that property. The prototype chain is a series of objects referencing each other, allowing for continuous searching of properties. If the chain is traversed and the property is still not found, undefined is returned. Object.prototype is the top-most prototype that all objects reference. Objects ca…  ( 7 min )

Picture this: you're hurtling down the M25 at 70mph, hands momentarily off the wheel whilst your car's Level 2 automation handles the tedium of stop-and-go traffic. Suddenly, the system disengages—no fanfare, just a quiet chime—and you've got milliseconds to reclaim control of two tonnes of metal travelling at motorway speeds. This isn't science fiction; it's the daily reality for millions of drivers navigating the paradox of modern vehicle safety, where our most advanced protective technologies are simultaneously creating entirely new categories of risk. The automotive industry's quest to eliminate human error has inadvertently revealed just how irreplaceably human the act of driving remains. MIT's AgeLab has been quietly amassing what might be the automotive industry's most valuable reso…  ( 19 min )

Introduction One day my friend kurokouji asked, innocently opening a rabbit hole: Can my Nerves-powered Raspberry Pi talk in Japanese using Open JTalk? Challenge accepted. I figured the answer was yes—I just didn’t know how yet. As Antonio Inoki once said: 元氣が有れば何でもできる (If you have spirit, you can do anything) So there was no reason not to try. Worst case, I’d learn something. Best case, the Pi speaks Japanese. Thanks to modern AI tooling, we can now explore rabbit holes without getting totally lost. The result is open_jtalk_elixir—a portable Elixir wrapper for Open JTalk, Japan’s classic text-to-speech engine. This library: Builds a native Open JTalk CLI during compilation Bundles the required dictionary + voice assets by default Exposes a clean Elixir API like this: Even if the destin…  ( 10 min )

Continuing from Day 007. Shorthand properties. A common shorthand is the font shorthand property, which lets you set several font properties. This declaration specifies font-style, font-weight, font-size, line-height, and font-family in that order: font: italic bold 18px/1.2 "Helvetica", "Arial", sans-serif; Instead of using the individual properties in separate declarations, you can use a shorthand property to include them all. It is good for making code clean and optimised. However, it is important to know that most shorthand properties let you omit certain values, and when those are omitted, they are set to their initial value, as defined in the CSS specification. You should check carefully when using shorthand properties because they override declarations elsewhere. For example: <h1 i…  ( 7 min )

Let's be honest. We've all been there right: Forgot to split changes into separate commits, ending up with a "mega-commit" that fixed a bug, added a feature, and updated the README all at once. Write vague, useless commit messages like "update files" or "fix stuff" that meant nothing to my future self or my team. Waste time staging and committing manually, breaking my flow state and turning version history into a chore rather than a helpful log. It's a bad habit I wanted to break, so I decided to build Gitcom—an AI-powered commit assistant extension for Kiro. The twist? I used Kiro itself as my pair programmer, design partner, and project manager throughout the entire journey. Here’s the story of how I built it and how Kiro’s unique features transformed my development process. One of the b…  ( 8 min )

Package naming and organization are fundamental aspects of writing maintainable code. How we choose to group files and modules impacts not only readability but also the ease of navigation and future development. In this article, we'll briefly explore how packages are used, trying to create some rules and give some reasoning about when it's a bad idea to create a separate package and when it's not. A package is one of the first concepts you encounter right after writing your basic "Hello World" program in Java or Kotlin. The simplest and yet misleading way to describe it is just as a folder structure used to organize code and prevent naming conflicts. And while it's partially true, it might give you the wrong perspective on when to actually use it. But let's stick to some kind of definition…  ( 14 min )

If you’ve ever worked with local development servers or peeked into configuration files, chances are you’ve stumbled upon 127.0.0.1. Often paired with the name localhost, this address plays a vital role in networking and software development. At its core, it’s your computer’s way of talking to itself. Let’s unpack what that really means and why it matters. Think of 127.0.0.1 as your computer’s private phone number. When an application dials it, the call doesn’t leave the room—it loops right back into the machine. In networking terms, this is called the loopback address, and it’s standardized across all devices. Whenever you type localhost in your browser, it resolves to 127.0.0.1 by default (for IPv4). This ensures consistency: no matter where you are in the world, this address will always…  ( 7 min )

Introduction Every developer has to start somewhere, and for me that meant turning my love for Harry Potter into code. I could have gone with Tic-Tac-Toe, or Blackjack, but I wanted something a bit more personal (and magical). A Harry Potter quiz felt like the perfect balance of fun and achievable... and let's be honest, adding house points makes everything better. At its heart, this quiz is built on a simple Question class in Python: class Question: def __init__(self, question_text, choices, answer): self.question_text = question.text self.choices = choices self.answer = answer Each Question object stores the text, the multiple-choice options, and the correct answer. The game then: Loops through a list of Question objects Prints the question and choices Use…  ( 7 min )

When you start writing C# code that needs to do things at the same time, two methods often come up: Task.Run Parallel.ForEachAsync At first, they both look like “magic ways to run things in parallel.” First things first: what do they do? 🟢 Task.Run Think of Task.Run as saying: 👉 “Run this one heavy piece of work on a background thread so my app doesn’t freeze.” It’s great for CPU-bound work like: resizing an image encrypting a file running a long calculation 🟢 Parallel.ForEachAsync This one is more like: It’s built for I/O-bound work like: calling multiple APIs downloading files querying a database It also lets you set a limit (MaxDegreeOfParallelism) so you don’t spam the server or your own machine. 📜 A quick history lesson When Parallel.ForEach was first introduced in .NET 4 (2010), …  ( 8 min )

When most people think of solar energy, they picture gleaming panels tilted toward the sun, converting light into electricity. While solar panels often take center stage in the renewable energy story, the real workhorses of solar grid integration often go unnoticed: inverters. These devices are the critical link between solar PV systems and the power grid. They convert the direct current (DC) produced by solar panels into alternating current (AC) used in homes, businesses, and utility grids. Yet modern inverters do far more than simple conversion. They provide voltage support, stabilize frequency, ride through faults, and ensure the grid can handle an increasing share of renewable energy. In the push toward 100% clean energy, smart inverters are proving to be the unsung heroes. Unlike conv…  ( 8 min )

1. HTML source code → Bytes When you request a webpage (https://example.com), the server sends raw bytes across the network (TCP packets). These bytes are not text yet — they’re just sequences of numbers. Example: the string in UTF-8 encoding is sent as bytes: 60 104 49 62 ( = 62 in ASCII/UTF-8). 2. Bytes → Characters The browser needs to decode the bytes into actual characters. It uses the character encoding specified by the server (Content-Type: text/html; charset=UTF-8) or by the HTML . Example: 60 104 49 62 → Characters . 3. Characters → Tokens Now the browser runs the HTML tokenizer. The tokenizer scans the characters and groups them into tokens, which represent meaningful chunks of HTML. Types of tokens: StartTag token: → an element node named h1. Text nodes: Hello World → a text node containing a string. Comment nodes: . 5. Nodes → DOM Tree Example input: Hello World Becomes a tree: Document └── body (Element) ├── h1 (Element) │ └── "Hello" (Text) └── p (Element) └── "World" (Text) Now this DOM tree is the structure your JavaScript code can traverse with APIs like document.getElementById(). HTML (bytes) → decode → characters → tokenize → nodes → structured DOM tree.  ( 6 min )

A solo developer's journey from over-engineered disasters to systematic AI-assisted development Every developer has that moment when their code becomes an embarrassing monument to over-engineering. Mine happened while trying to build Secondary Mind's visualization feature using the standard Kiro spec-to-code process. The result? A bloated, non-working mess of abstract interfaces, placeholder functions, and theoretical solutions that solved exactly zero real problems.
